Terk Hdr-I High-Definition Indoor Radio Antenna Review

Terk Hdr-I High-Definition Indoor Radio Antenna
Average Reviews:

(More customer reviews)
My HD radio is a Sony XDR-S3HD. So this comparison is only true for this radio and my location (just north of Washington DC). I tried the accompanying wire and dipole antennas first, and then tried this Terk HDRI Antenna and a Philips Magnavox MANT-110 Indoor Passive Antenna. The Terk box says it is specifically for HD radio. The Philips box says it is for VHF/UHF/FM/HDTV.
The dipole worked best overall of the two included with the Sony but I experienced a number of drops when there was movement, either by myself or even my cats, on the far side of the antenna relative to the general direction of the station's tower that I was tuned into. The Terk (with the gain set to the maximum) and the Philips both worked better in this regard resulting in practically no drops in the same scenarios.
The Terk costs 36.14 on sale; the Philips costs 9.99. So the Philips wins on price. Here's the shocking thing. When I tried to tune into WAMU-HD3 or WTOP-HD3 or WCPS-HD3, the Terk had trouble picking up the signal unless I was positioned just right in the room (for example, if I was 5 feet from the antenna but not 3 feet, or if my TV was on, or...). The Philips has no problem picking up these stations regardless! This makes the Terk very much a disappointment. The Terk did not pick up any additional HD channel 2 stations compared with the Philips (the ones I can't pick up currently on a regular basis are WWWT, WPGC, WBIG and WPRS). So if you're having problems with the wire or dipole antenna, then my suggestion is to pick up the Philips or some other cheap indoor FM antenna and forgo spending money on this overpriced Terk.

Terk Technology HDTVi VHF/UHF HDTV Indoor Antenna Review

Terk Technology HDTVi VHF/UHF HDTV Indoor Antenna
Average Reviews:

To start, your antenna is only as good as the signal that is reaching your home! The HDTVi does a great job on receiving UHF signals, a very good job on VHF signals. From alot of reviews of antennas, it would appear people are clueless on HDTV reception. For your local reception, I'd check out the forum at the following address. They have information and experience going back a couple years on HDTV reception in many cities. So before trying to wrestle with antennas, first make sure you aren't searching for nothing. When I started, I couldn't find ABC not because of the antenna, but because the station was transmitting for four days! http://www.avsforum.com/avs-vb/forumdisplay.php?s=7e85bb49c56fa3787e7ed73e6ec7473d&forumid=45
I tried 5 antennas, an old one, the HDTVi, the Terk TV5, Radio Shack amplified antenna (15-1880), and Philips' amplified antenna (SCA050). The best reception was received on the Radio Shack, however, the amplifier needed to be higher for reception of CBS while it had to be lower for FOX or FOX wouldn't come in. This was bothersome. I was also able to get a weak NBC signal unlike any other antenna I had, but the signal just wasn't strong enough. The TV5 had mediocre coverage. It was able to get UHF decently, but it was fighting to get upper and lower VHF. The Philips and HDTVi had similar reception, but the HDTVi wasn't amplified which meant I would have more options regarding moving the antenna around, such as placing in the attic without worrying about plugging it in.
Ultimately, as far as UHF was concerned, each antenna had similar results. It was in VHF that the antennas were a bit different. As far as ranking the antennas for reception:
1) Radio Shack's 15-1880 Best
2) Terk HDTVi Very good
3) Philips SCA050 Very good
4) Terk TV5 Decent
The Terk HDTV wins out because of the lower price, the fact that it is unamplified, had very good reception, and took up the least space. One last comment would regard the coax cable you use. I tried using some coax (about 30 feet) just laying around to hook up the receiver to the antenna. The signal just wouldn't carry the distance. When I used a much higher quality coax that came with the installation of my sat dish, the signal came in loud and clear.
If possible, I'd recommend get a few antennas at the same time and make sure you can return them, most stores have 30 day policies. Plan on spending a week on gaining the best reception with the best antenna for your home.

With over 1,000 stations in more than 200 markets broadcasting digital television as of 2003, 9 out of 10 households can now receive free high-definition (HDTV) signals when using the right antenna in conjunction with an integrated HDTV (or with a set-top box and an HD-ready television). Most antennas are large and unwieldy and need to be mounted outdoors or in a cramped attic. This is not an option if you live in an apartment or condo, or if you don't want the hassle of installing an antenna yourself. The solution? A quality indoor antenna that can pick up all local HDTV channels; one that will look great next to your television, and one that is easy to install: Terk's HDTVi indoor antenna.At the time of its release, the HDTVi was (and may yet be) the only indoor HDTV antenna optimized for both UHF and VHF reception, channels 2 to 69. The HDTVi elegantly solves the aesthetic challenge of integrating a log-periodic-type element assembly in an indoor antenna. It's tuned for optimum HDTV reception with a unique design that uses log-periodic elements and dipoles for receiving both UHF and VHF HDTV broadcasts, bringing you more stations than lesser antennas.You can easily route the antenna's output cable in 2 directions (front or back) for flexible cable management, and the antenna connects easily to your set-top box or television (integrated HDTV--with built-in ATSC tuner--required for direct connection).Its high gain picks up distant stations and its high back-to-front ratio rejects unwanted signals. You can mount the UHF antenna element vertically or horizontally, as experience dictates.What's in the Box Antenna with integrated 75-ohm cable, instruction manual, and warranty information.

C. Crane FM Reflect Antenna Review

C. Crane FM Reflect Antenna
Average Reviews:

(More customer reviews)
Amazon's price for this antenna was the best I could find. I ordered it on a Sunday before a Monday holiday and it was delivered the following Wednesday via their Super Saver free shipping, which I considered to be excellent service. This antenna looks better than a twin-lead dipole antenna, appears to be well-made, comes in an attractive box with a balun coil (matching transformer) for connecting to screw terminals and also an alligator clip for hooking it to a built-in antenna.
Since this antenna has received mixed reviews from other users I decided to be as "scientific," as my skills and equipment would allow. I used my training as an FCC licensed broadcast engineer to compare it to the standard twin-lead dipole antenna that was included free with my tuner. I had already oriented my existing dipole antenna for optimum reception, using my tuner's signal-strength indicators. I then used my tuner's scan mode to see how many stations it could find and I carefully wrote down the frequency and signal strength for each of the many stations that I can receive. Since I live about halfway between New York City and Philadelphia, my FM dial is crowded with stations.
After establishing a base-line of performance with my ordinary dipole antenna, I replaced it with the C. Crane FM Reflect Antenna and experimented with dozens of antenna positions to obtain best reception. Remarkably, mounting the C. Crane FM Reflect Antenna in the exact same position and location, that my twin-lead dipole antenna had been installed, gave me the best performance. After this optimum positioning, I once again used my tuner's scan mode to see how many stations it could find. I then carefully compared the signal strength from each station that my tuner found using the new antenna, with the signal strength that I had received with my previously-installed antenna. Although I saw no indication of a stronger signal on any of the existing stations, I was able to pick up two more stations in my tuner's scan mode with the new antenna.
As a percentage of the large number of stations that I could already receive at my location, I considered two additional stations a very small improvement. The difference easily could have been due to minor changes in atmospheric conditions between the tests. It was certainly not as dramatic as the improvement that I expected when comparing a $3 antenna with a $30 antenna. If you're using a good twin-lead dipole antenna and have adjusted its position for best reception, I believe that you'll need to upgrade to an outdoor antenna, such as the Winegard HD-6000 FM Stereo Antenna, to get a noticeable improvement. I could not find that the C. Crane FM Reflect Antenna is significantly better.
To understand why the results turned out as they did, it might be helpful to understand how antennas work. The most effective antenna elements in the FM and TV band are the length of the radio wave that they're tuned to receive. Our FM band extends from 88Mhz to 108Mhz, which represents a wavelengths from slightly more than 109 inches to slightly more than 134 inches. The higher the frequency, the shorter the wave.
A typical folded dipole antenna is about 61 inches wide, which is half the length of the average FM radio wave. Since the dipole is folded onto itself, it has an effective antenna length of about 122 inches, which is the average between the 109 inch and 134 inch wavelength extremes of the FM band.
There are several ways to increase the gain of an antenna. One way is to increase the number of active antenna elements that are exposed to the radio waves and connect them together. Another is to use a reflector to concentrate the radio waves onto the antenna. Satellite antennas, for example, reflect and concentrate very short waves onto a rigid dipole antenna by using a dish. Outdoor Yagi FM (and TV) antennas use multiple elements connected in tandem with reflecting elements in the rear to focus the antenna's sensitivity in a single direction. Such antennas are very efficient because they use both multiple elements and reflectors to increase gain.
Ultimately the Crane antenna, no matter how attractively it may be designed and packaged, cannot defy the laws of physics. It has only a single active T-shaped folded antenna element which is exactly the same as an inexpensive twin-lead folded dipole antenna. It is, therefore, not surprising that several reviewers including me, who have compared it to the cheap variety, have found that it gives no better reception.

Whether you listen to a portable radio or a top-of-the-line stereo receiver, the quality of sound coming from an FM station is dependent upon the stations signal strength in your area. Adding an FM antenna can help greatly, so be sure to select the best FM antenna for your needs. The FM Reflect Antenna will work with any portable or stereo receiver. This antenna incorporates a new dipole design for maximum gain across the entire FM broadcast band. Up to 213 percent more powerful than a standard dipole antenna, it covers the entire FM band with an almost flat response, where standard dipoles start to fall off near the end of the band. Many FM stations now broadcast their signal with circular polarization. The FM Reflect Antenna is the only FM antenna that can be adjusted to take advantage of this. It is not affected as much by surrounding objects and people as other FM antennas are.

Channel Master 4221HD Multi-Bay UHF Short Range HDTV Antenna Review

Channel Master 4221HD Multi-Bay UHF Short Range HDTV Antenna
Average Reviews:

(More customer reviews)
I initially made the mistake of thinking all expensive antennas were created equal. Needless to say, my first antenna was a $100 purchase that worked no better than my old rabbit ears.
I then made the decission to "step up" and purchased a Radio Shack antenna from the "electronic experts". It was touted as an attic antenna but was really too cumbersome for the attic and again provided no more value than my rabbit ears.
Fed up with making returns, and noticing that being in a hurry was costing me time, I finally decided to do some research. After much reading, I decided the 4221 based on its rating was going to be the right thing. I have it installed in my attic and could not be happier. It is a very manageable size and most importantly, it brings in all the channels flawlessly! After the two previous failures I could not be more thrilled. Price is not the key. It was cheaper than the two previous attempts by about half the cost. . . And the best news. It works!
You will want to check on the requirements for your area. A midrange UHF was perscribed as the right thing based on broadcast signals in my area. One also needs to ensure the antenna is pointed in the right direction. Most high gain antennas are directional as is the 4221. If you are looking for a midrange UHF, look no further.

Philips MANT940 UHF Digital and Analog Indoor/Outdoor Antenna Review

If you subscribe to satellite or cable you may be surprised to learn that in many area, over-the-air digital TV offers better picture quality and may offer some unique channels not found on your cable system. But getting great over-the-air TV requires a good antenna. Over the years I've tried the following:
-Traditional roof antenna with rotor: Works great but antenna must be turned to get stations in different directions.
-Simple indoor bow-tie or loop antennas: Very cheap to buy, but only pick up the strongest channels. Very prone to interference that can cause picture freezing and break-up.
-Indoor rabbit ears with UHF: a little better than the cheapies, but still difficult to adjust and prone to interference.
-Radio Shack Double Bow-Tie antenna: This one is no longer available, but it is legendary. It looks like a gold screen on legs, with two gold bow-ties mounted in the front. (Very '50's in appearance.) This is a very good indoor UHF antenna (and all the digital/HD channels in my area are UHF.) It provides good, stable reception on most of my local channels, but sometimes has problems with the handful that are in a different direction. It's not a very pretty antenna, but at about $16 it was pretty cheap.
Recently I got a new TV for the bedroom and after looking around, I decided to give the Philips MANT940 a try. It fit my criteria:
-Relatively inexpensive (I paid just under $40).
-Small and unobtrusive
-Can be used indoors or out.
-Got mostly good reviews from consumers in online reviews.
I put the antenna on the top shelf of the bedroom closet. The included 20 cable was plenty long enough to reach the TV.
So far I'm very pleased. This is the best antenna I've used so far. All of my local stations come in clear and stable without making any adjustments to the position of the antenna. I'm even getting a station from the next town over that previously only came in with a broken signal. I'm very pleased and would recommend this antenna to anyone living within 20-to-30 miles from the TV stations they want to receive. I'm not sure how well it would work at greater distances.

Terk HDTVa Indoor Amplified High-Definition Antenna for Off-Air HDTV Reception Review

Terk HDTVa Indoor Amplified High-Definition Antenna for Off-Air HDTV Reception
Average Reviews:

(More customer reviews)
Having spent a bundle acquiring a Sony LCD HDTV and upgrading our Dish service to include its limited set of HDTV channels, we were anxious to see what an Over-the-Air Antenna might add.
In all, we tested 5, including the highly rated Zenith log periodic (about $40 at Sears), an amplified Samsung (about $99 at Best Buy), an outdoor Terk 32 (about $80 at Circuit City), our old roof mounted VHF/UHF antenna (circa 1985), and the amplified Terk HDTVa (about $50 at Radio Shack). The Terk HDTVa won hands down; no contest, blowing away the much touted Zenith.
We live in the sparsely populated, low hill countryside of Western Massachuetts. The THDTVa effortlessly brings in between 20 and 30 analogue and digital (incl hdtv) channels broadcast most from 12 to 45 miles away, and some as far as 65+ miles away in Connecticut. Some digital OTA channels actually come in more sharply than some of the (Dish) satellite digital channels.
This is definitely a keeper: a great value, gem of an antenna. So good, in fact, we are debating giving up our $50/month Dish service, putting $15 of that to Netflix to replace HBO, and banking the remaining $35.

Basic Indoor Antenna Review

Basic Indoor Antenna
Average Reviews:

(More customer reviews)
I'm a first timer at getting OTA HDTV. This has been an experiment in progress for the past 5 weeks. I have gone through four antennas (they are all here as I write this) before finding something that's satisfactory (rather than tolerable).
I live around 25 miles from Manhattan, where the towers of most TV stations are located. I am also aware of the directional information from [...], and have experimented accordingly with its effects on reception. My apartment's windows all face north, while the signals all comes from southwest. I cannot get signals from where it comes from, and thus needed to get signals from deflections perhaps off nearby buildings and trees. It's a very poor circumstance for over-the-air reception, maybe just slightly better than being underground. Signals are weak, and are affected by weather. Stormy and windy days have shown effects at disrupting signal reception.
With this said, and without going into much detail, let's talk about the antennas. Now all these antenna have been tested with the same equipment, setup, directional adjustments, location, etc. etc. and have been tested through good an foul weather, day and night, to observe differences.
1.Terk HDTVa Terk HDTVa Indoor Amplified High-Definition Antenna for Off-Air HDTV Reception- After reading some rave reviews and high ratings at [...], log periodic types (looks like a fishbone) seems to be the way to go. I got the Terk HDTVa first, thinking that the amplification and VHF antenna should nail my reception problems at the start. However, after more than two weeks of fidgeting around ad nauseam (directions, locations, amplifications, different devices, etc.), I only managed to pick up two ATSC channels' signals, and even those don't have strong enough signals to display anything. I thought maybe it's just my poor location, and that I should probably give up on the attempt. The included in-line amplifier dongle doesn't work at all. Powering it on makes no difference in signal strength readings, which hovered around 5-10%.
It is well built, looks nice, good concepts, but it just didn't work.
2.Phlips PHDTV1 Philips PHDTV1 Digital HDTV-UHF Indoor Antenna- The venerated "silver sensor" which was previously sold under the Zenith brand also had great ratings and reviews. It's in fact nearly legendary. I decided, in desperation, to try it out, even if it doesn't have amplification. It seems all my local HD channels are in UHF anyway, so I won't miss the VHF dipoles.
The unit has startlingly poorer build quality compared to the Terk. It has paint bubbles, hairs and dusts trappings in the paint, sharp edged cheap plastics and much thinner metal blades that's covered in oil and has some dings and bendings. I wasn't impressed with the quality, and didn't expect much from it as I set it up.
To my surprise, it picked up 9 working channels (note: the terk got two channels' signals, but they didn't work) from the start, even if it's randomly placed. It's thrilling as it was the first time I saw OTA HDTV. After some adjustment and location experiments, I was able to receive 19 channels. However, not all of these channels work well given the same direction.
The directionally sensitive antenna needs to be adjusted as I switch channels. e.g. NBC and CBS seems to work well in one direction, while ABC has its own favorite direction, which works also with FOX. I tried as best as possible to find a compromise point where everything works. I couldn't. It just needs to be adjusted constantly.
The transmission is often dogged by reception fluctuations. Signal quality tend to fluctuate quite a bit, especially affected by weather. That means the TV playback would get choppy at times, with its severity dependent on the direction I point the antenna at. I didn't think fluctuating signals was a characteristic until I tried the latter two antennas later. I also found that I had to constantly play with the directional positioning to get a stable signal from each of the stations.
It works, and I was impressed, but then in retrospect it could only be best described as a "tolerable" HDTV experience as I struggled for a smooth signal delivery.
3.RCA ANT111 Basic Indoor Antenna- While shopping in stores, I saw this basic and classic RCA loop/dipole antenna for less than $[...]. I couldn't resist the temptation to try it out, just for the heck of it. It is also a different type of antenna than the previous two.
Again, I was surprised. This cheap antenna worked well, especially considering how it's only a fraction of the price of the two I'd tried. I ended up getting 17 channels, a few less than the PHDTV1, with the same location and setup. Some channels also don't work, even if signals were detected. The quality of the signals seems to be the key.
So what's so special about it? It strangely had better signal delivery for the channels that worked. It's not as choppy, and quality level is very steady. It is also not as affected by directional positioning. I was for the first time able to view FOX, ABC, CBS, NBC without adjusting the antenna. However, the lack of directionality also makes it ambiguous when I lost the signal. It seems that there's no "favorite direction" for the channels, which also means I can't pull in stronger signals at my choosing. It is also quite susceptible to weather changes, particularly wind (which probably affected signals reflected by trees?)
The signal strength also seems to be a little weaker, though the signal quality tend to be higher in general. That probably contributed to the smoother video delivery. It also tempted me to get a similar design that has amplification.
4.Philips MANT510 Philips High Performance Amplified Indoor Uhf/ Vhf/ Fm Antenna- This unit has a "digital TV optimized, patent pending UHF panel array". I thought I'd try it out just for the slightly different antenna design, if not just for the adjustable amplification.
Well, it works, and works quite well. The antenna doesn't work without power, and with amplification turned off it works a little less than unpowered PHDTV1 and ANT111. Yet with the amplification turned on, I get 24 channels, with strength up to 81% (compared to 3-10% unamplified, and quality consistently above 60 and usually in the 70-90%+. That generates the most reliable video delivery of all the ones tried.
While thunderstorms still managed to distrupt signals, it's much less often and only momentarily. I also don't have to worry about hunting for signals as I just point it in one general direction and I get everything but three NJN channels (they are even further from here.. maybe a good 50 miles).
I finally can just set the antenna and forget it. It lets me focus on the programming rather than antenna adjustment. While it needs to be powered, it gives me the confidence to finally enjoy HDTV, rather than tweaking and tolerating it. It's good enough that I can probably stop searching. I hope it'll be helpful to you who may be going through the same purchasing decision nausea as I have.
