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.
