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.  (When installing a splitter with this amplifier it must be a power passing splitter, most common splitters will not pass power.)

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 3G/4G/5G 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, pixelation or even channel loss, and can be especially disruptive when an amplifier is used with a TV antenna.
