Winegard AP-8275 Preamplifier High Gain Low Noise 28dB UHF 29dB VHF for HDTV Antennas Review

One of the highest-gain mass-market TV preamps you can get, good in fringe areas where all the TV signals are weak; however, if you also have a strong TV station nearby its signal can overload any high-gain preamp and degrade all channels. Also, nearby lightning strikes within a few blocks can blow preamps even without direct contact.
This one from ANTOnline worked OK, but be aware that Winegard has outsourced production to China and it seems that reliability of this and all items formerly made in the U.S. have fallen drastically (not just my opinion!) - this is the 2nd Winegard preamp I've bought and the first one (not purchased from ANTOnline) was DOA and had to be replaced under warranty with the added postage expense. So, if you get a Winegard preamp that works that's good, but don't be surprised if it doesn't. Geez, even the simple packages of pre-cut RG-6 TV coax cable you need to wire this preamp up can't be trusted if they come from China - I bought 2 separate U.S.-branded packs now made in China and one was shorted and the other open, I had to cut the connectors off and put on new ones. And that wasn't all - I also bought a new antenna rotator that had been outsourced from the U.S. to China, and it broke down in just 2 days! Give us a break! It almost seems like a conspiracy!

Terk AF-9330 AM/FM Indoor Amplified Tower Antenna Review

Terk AF-9330 AM/FM Indoor Amplified Tower Antenna
Average Reviews:

(More customer reviews)
I was hoping to improve reception on a few stations , so I decided to replace the twin lead dipole (passive) antenna that came with my new tuner with the Terk Tower. I have the AM Advantage loop and that works fairly well, so I figured this powered antenna would be a lot better.
Well, bad reasoning. On FM, it doesn't work NEARLY as well as a 32" piece of plain old wire on any of my radio recievers. In some cases, stations that could be tuned reasonably well with *nothing at all* attached to the FM inputs, and no internal antenna, could no longer be received with the Terk Tower attached.
Those that could be tuned with the antenna attached had grotesque distortion. This despite turning the gain adjustment dial in either direction. It was functioning, as at low levels of gain, the station dropped off completely, and definitely changed as you moved it. So it wasn't just broken. I could get barely acceptable reception on a few stations with micro-fine adjustments of the dial. But even at best all stations had all sorts of fuzz and dropouts. You could turn it up enough to swamp the receiver ACG circuit, but the distortion never goes away as you turn it down the point of losing lock completely.
On AM, it doesn't make it worse, but it doesn't help, either. On all the weak stations I have tried, I simply can't tell the difference in the results. Once again, fiddling with the gain control changes it, but at maximum boost, it's pretty much what I was getting with the the teeny little loop antenna that bolts to the back of the tuner. At lower gain settings you just can't hear the station at all.
For all intents and purposes, it just doesn't seem to work, I tried it on 4 different tuners/radios in 4 different places in my house, and in every case it made the FM reception MUCH worse than the stock antennas, and AM reception no better than the stock or internal antennas. I'm probably going to break it open and try attaching different lengths of wire in place of the stock antenna, and see if that helps. But I get the impression that the booster amplifer just isn't up to the task of passing 107.7 MHz., and introduces too much distortion at FM freqencies. It almost has to be - because a plain old wire that length is MUCH better.
Even though it was pretty inexpensive, I was very disappointed with this antenna. You'll get FAR better reception with a bent coat hanger. And that's free with your dry cleaning.
(addendum - I finally broke my antenna open, and now it's clear why it doesn't work on AM any better than a stock antenna. It's because inside the tower, for AM, is a small, unamplified, loop antenna! It's not even connected to the circuitry. Which begs the question of why turning the dial affects the AM performance. I speculate that the AM loop and the FM amplifier are interfering with each other - and that the AM is getting into the FM amp, causing modulation at the FM subcarrier frequency, hence, really fuzzy FM reception - and also dragging energy out of the AM loop more or less depending on the FM amp setting. BTW, the FM antenna is a piece of bare copper wire running the length of the antenna. Short answer is still the same - it's junk, don't waste your money)

Terk FM Edge Dual-Drive Amplified FM Antenna Review

Terk FM Edge Dual-Drive Amplified FM Antenna
Average Reviews:

(More customer reviews)
I live in TX, about 80 miles from Austin and San Antonio. With a simple dipole antenna I can get about 3 reasonable stations on my Pioneer tuner. I thought I would try the Terk to see if a powered antenna would pull in a few more stations. Well, it didn't. In fact, some of the marginal stations that just weren't quite good enough with the dipole were worse or gone with the Terk. I fiddled with it over a few days, trying different times of the day, or different orientations ..... nothing helped. So I returned it for a refund. I think these units are overhyped. From what I've heard more people are disappointed than thrilled with the results. As always...."Your mileage may vary" but it was no good in my situation.

Terk Amplified Indoor AM/FM Antenna (PIB) Review

Terk Amplified Indoor AM/FM Antenna (PIB)
Average Reviews:

(More customer reviews)
I live in what is called a "fringe area" on the Outer Banks of North Carolina. We have a handful of local FM stations, but the best radio is just 50-90 miles north in Hampton Roads, VA. FM stations that come in well on your car stereo from these areas never seem to make into office and home stereo systems.
The TERK promises to amplify a signal if it's present. I live in a 3 story wood frame house, on top of a 30 ft sand dune, so altitude should be excellent for this type of antenna.The wood frame house should not block FM signals. No dice. 50 kw FM atations 40 miles north (Hertford, NC) and south (Englehard, NC) came in no better on the TERK than on a typical factory supplied dipole. 100KWer's in Tidewater such as WMYK (93.7), with a 1000 ft tower 50 miles north are barely registering on my Sony tuner. These stations come in fine on my Bose Wave and assorted portables. High end systems lack the "sensitivity" of smaller radios when it comes to boosting FM signals, and the TERK can't seem to overcome that problem.
My advice? If you want a solid signal for your high end system, and you live in a fringe area, go with either an outdoor TV antenna, or if possible, mount one in your attic. The FM radio band in wedged right between TV channels 6 and 7, so any outdoor TV antenna will do the trick. If you are confined to an apartment, I have no advice other than "save your money" and try other alternatives.

Truspec 18-25DB Sloped Distribution Amp Review

Truspec 18-25DB Sloped Distribution Amp
Average Reviews:

(More customer reviews)
I installed the amplifier between my outside antenna and my TV, about a 30ft run. Setup is straight forward. Plugs into the wall and is installed as a pass thru for the cable. I was trying to get a few of the weaker stations to have a more stable signal. This box had no affect what so ever that I could see. The meter that comes with my TV registered the same with or without the box attached no matter what position the switch was in. Waste of money for me, considering a bigger antenna now.

Channel Master CM7777 Titan2 VHF/UHF TV Antenna Preamplifier with Power Supply (Grey) Review

Channel Master CM7777 Titan2 VHF/UHF TV Antenna Preamplifier with Power Supply (Grey)

(More customer reviews)
I purchased this amp over a year ago and found that it was just the ticket. I researched my purchase on several websites and determined this was the best within an afordable range (There was one overseas with less noise but it was over double the cost). I had a cheap amp from a home improvement store that gave me reception but with the upgrade to HDTV I was getting dropouts more than I would like. I purchased this amp and no more drop outs, it gave me a boost in 20 points on my Sony Bravia digital reception over the cheapo booster. I suspect the negative reviewer installed it wrong. There are separate inputs for VHF & UHF that you can combine to one input but if you do not you would eliminate your VHF channels (2-13) or UHF (13-69) entirely which would explain loss of these channels.

The Channel Master CM 7777 is a high gain, low noise preamplifier used for weak signal areas to allow a weak signal that is present at the antenna to be amplified to a viewable strength. This TV antenna preamplifier works best for persons in weak signal areas and is subject to overdrive if used in areas with fairly strong signals. In stronger signal areas our medium gain preamplifier, the CM 7778 is a better choice.
