The p/n APA7777 television antenna booster (preamplifier) will amplify digital and HD signals received by your antenna.
This antenna amplifier 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.
WARNING - The p/n APA7777 is recommended for professional installers only. This amplifier has a high gain output and can result
in over amplification if not used in the appropriate scenario. Over amplification can cause issues with a television
tuners ability to receive and display some or all channels. An ideal scenario for the p/n APA7777 is an application where ALL
broadcasts towers are 80 miles, or more, from the broadcaster and a splitter is used to distribute to multiple televisions. Just
one high power signal or broadcaster that is close in proximity can cause over amplification resulting in the loss of
The p/n APA7777 is a high quality, high gain amplifier and is subject to misuse, less than 1% of the p/n APA7777's
that are returned are actually defective.
We recommend the p/n APA7778 amplifier for consumers that do not have the ability to measure or calculate signal
levels. In 98% of consumer applications, the p/n APA7778 is the best choice and will outperform every other professional
grade amplifier on the market without having to worry about over driving strong signals.
