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.

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).

Overachiever October 11, 2018
Reviewer: Vince from Phillipsburg, NJ 08865  
I have two long range HDTV antennas connected together and aimed in different directions to eliminate rotating the antennas. One is an UHF HDTV model while the other is a VHF/UHF HDTV model. They are connected to the designated inputs on the preamplifier. All cabling is Quad-Shielded Coax Cable. The preamplifier switches are set as follows: UHF Input = Separate; FM = On and Gain = Low. This preamplifier takes your TV experience to new heights. It gives you exceptional HDTV reception. The colors are true to life and the images have clarity. A competitor's preamplifier did not even come close to this device. I would highly recommend this product.

Channel Master Amplify+ Adjustable Gain Preamp July 30, 2018
Reviewer: Paul Martin from Southwestern Pennsylvania  
I purchased the Amplify+ Adjustable Gain Preamplifier from Channel Master about a month ago and finally was able to install the item. The product replaced the Old Dual Input Model 7777 amp. I adjusted the gain to the high level and found the performance to duplicate the excellent results of the previous unit. In addition, I found the new model to be superior in terms of the weather proof housing. I am very satisfied with the purchase and hope the product is as reliable as the earlier highly regarded preamplifier.
