Description Technical Specifications FAQ's & Support Docs
 

Amplify+ is intended for outdoor professional use, including multi-dwelling units and commercial applications. The product provides separate UHF and VHF inputs for two-antenna, band-specific installations, as well as a switchable FM trap.

Amplify+ is an outdoor preamplifier designed for mast-mounting with the TV antenna(s). Professional installers may choose options for High gain, Low gain, FM signal blocking and band-specific dual antenna use if required.

Unlike the consumer-ready Amplify product, Amplify+ does not include a USB powering option for indoor use.

Outdoor Heavy-Duty Housing

Amplify+ is constructed of a die-cast metal housing with weatherproof ports to support outdoor installations in extreme weather conditions.

Adjustable Amplification

Amplify+ provides adjustable settings that allow the installer to select the appropriate gain required for a specific installation scenario, eliminating the potential issues encountered from either too much or too little gain. The internal switch can be placed at either a High or Low setting.

Adjustable FM Trap

Amplify+ provides a trap mechanism to block unwanted FM Radio signals from FM-enabled commercial TV antennas, which can cause interference with UHF and VHF television signals. Pass-through of FM signals can be enabled or disabled via an internal switch.

LTE Filtering

Like the consumer-ready Amplify product, Amplify+ provides LTE signal filtering. The proliferation of LTE signal towers and connected LTE devices are a growing cause of intermittent disruption of over-the-air broadcast television signals. These disruptions can result in weak signals, pixilation or even channel loss, and can be especially disruptive when an amplifier is used with a TV antenna.

Amp May 14, 2019
Reviewer: Tom from Buffalo, NY  
Works as promised.   You will have to experiment with both power settings to see which works for you best.  I have mine set on high.  Brought the stations in without overpowering them, got rid of pixalization.

Channel Master review May 14, 2019
Reviewer: Anonymous Person from Yadkinville, NC  
Tried an inexpensive amp to start with, couldn't pick up 60 to 70 miles range stations. Decided to give this amp from Channel Master a try. Night & day difference. Picked up these outlying channels plus about 7 stations that weren't even on my expectation list. Definitely worth the investment for cord cutter living outside big markets.

Preamp works like a champ May 14, 2019
Reviewer: Brian from Midwest  
I have one lower power station I can't tune. My other stations are all strong (98/100 on the TV signal strength meter). I installed my CM 7778HD preamp in the basement, not as recommended on the mast right below the antenna. Now my high power stations are all at 98/100 and my lower power station is 50/100. Life is good!
I liked my results so much I bought another one for my Yagi antenna.

Part of bundle with Extremetenna 80 April 17, 2019
Reviewer: Jim W from Livermore, CO  
Wanted a more powerful preamp since we are in a bowl and mountains around us are higher and TV antennas are 70 to 80 miles away, with no line of sight.  We now have 19 channels and by all info available we were not supposed to get ANY.  We are pleased with our choice with Channel master and all the Help Jordan gave us and worked with us.

Works great! February 11, 2019
Reviewer: Tom from Texas  
I had an older version of this preamp and after years of faithful service, I started to get pixilation and signal drop.  I have separate VHF and UHF antennas, so needed the dual inputs this provided.  Out with the old, in with the new, and TV signal strength is better and I'm back in business!  I like the fact it has built-in LTE filtering as well (was not available in my old preamp).
