AV-587
Antenna Accessories | Diplexer, Splitter
The AV-587 antenna coupler is an antenna signal splitter/diplexer providing three outputs from a single antenna. One output provides a combined VOR/LOC/GS signal. A second output provides a combined VOR/LOC signal. And a third output provides a GS signal.
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 one newer navigational radio and a second older legacy navigational radio, the AV-587 is the article that will provide the necessary signals to both radios utilizing a single antenna.
