antenna coupler - AV-586


Antenna Accessories | Coupler

The AV-586 antenna coupler is a signal splitter providing two outputs from a single antenna. The necessity of bringing this product forward comes from advancing technology in avionics. Newer designed navigational radios have only one antenna input to receive all three (VOR/LOC/GS) signals whereas older legacy radios had a separate antenna input for the VOR/LOC signal and another antenna input for the GS signal.

In an aircraft instrument panel with two newer navigational radios the AV-586 is the article that will provide the necessary signals to both radios utilizing a single antenna.
