Features
- Simple clip on attachment fits any A320 amplifier
- Install and remove without tools
- Simultaneous connection of two separate antennas
- Low Noise Amplification for UHF SATCOM operation
- Provides approximately 10dB of gain
- Utilizes existing A-320 DC power and RF cables
Overview
The lightweight A-320DPA installs without tools. When needed, operators simply clip on the
A-320DPA to existing lanyard pins on the A-320 and unclip when desired. It's that easy.
The adapter allows for simultaneous connection of two separate RF antennas for differing
frequencies. It also functions as a Low Noise Amplifier (LNA) for UHF SATCOM transmission.
Applications
Any user of the A-320 20-watt amplifier that desires dual port capability can benefit from
this adapter. The snap on design allows the operator to install without tools when there is
an operational requirement including when an LNA on UHF SATCOM is desired.
