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!

Winegard HDTV Antenna Preamplifiers are engineered to the highest specifications ensuring consistent signal amplification performance. The Winegard AP-8275 preamplifier is specifically designed to amplify DTV signals at the antenna 29 dB on VHF frequencies, and 28 dB on UHF frequencies, boosting the digital signal to overcome any cable or splitter loss in your TV antenna system and minimize dropouts. In a low signal area, a setup with long cable runs, or a multiple TV system, the AP-8275 preamp may be the solution you need for a perfect digital picture. Winegard AP series preamps are constructed of tough, high impact ABS material and the zinc plated steel hardware ensure electronic parts are safe from the elements. They feature a selectable and tunable FM trap to reduce strong local FM stations from interfering with your perfect digital picture. They also employ specialized circuitry featuring an ultra fast recovery diode. Power supply and mounting hardware included. Note: A preamplifier will not pull in extra signal, it can only amplify the signal reaching the antenna.

Winegard AP-8700 Preamplifier High Gain Low Noise 19 dB UHF 17 dB VHF for HDTV Antennas Review

TV Antenna Source said this about install of TV antenna amplifier.
The TV signal from your TV antenna becomes weaker as it travels through the coax cable to your TV.The farther it must travel the weaker it becomes. Signal splitters also weaken the signal. The more times the signal is divided the weaker it becomes. The splitter itself creates the signal loss, it doesn't matter if the TV's are on or off or even if all of the connections on the splitter are used the loss still occurs, it's called insertion loss. The line loss that occurs getting the signal from the TV antenna to the TV or TV's can be overcome by installing a preamplifier near the TV antenna amplifying the signal before the signal loss occurs.
The degree a signal amplifier increases the signal strength is measured in decibels (dB). The higher the amplifiers dB rating is the greater the strength of the signal is increased. "Wait a minute, I know what your thinking "I'll just get the biggest high output amplifier I can get and that will solve all my problems. I have one word for you, OVERLOAD. When too much signal is present overload can and does happen. Signal overload can occur in the amplifier, the TV tuner or both. Use the guidelines below, to select the proper amplifier for your system.
Selecting the correct TV antenna amplifier is a simple mathematical process.
Add-up the total amount of signal decibel loss that will occur as the signal travels from the TV antenna to the TV with the longest cable run. Add the signal loss from the cable length and any splitters between the antenna and the TV. Choose the amplifier with the dB gain rating that is from 5 to 10dB greater then the total loss. EXAMPLE: 100 feet of coax cable and a 2 way splitter have a signal dB loss of 8.7 dB. Also VCR's and other such devices that the signal travels through create minor signal losses. A perfect amplifier match for the above example would be the Winegard AP 8700. The 8700 amplifier has a gain rating of 19dB.
AVERAGE LOSS PER 100 FEET OF RG6 COAX CABLE IS 5 dB
2 way splitter3.7 db
3 way splitter7.5 db
4 way splitter7.5 db
6 way splitter13 db
8 way splitter13.5 db

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

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.
