Q: Regarding the RAMI AV-574 coupler: Can you hook one of the navs to the localizer? VOR / LOC / Glideslope

The AV-571 will provide (2) VOR/LOC outputs and (1) GS output to the panel mounted NAV receivers from (1) VOR/LOC/GS antenna.

Q: Can i use the AV-571 to connect to the GS, VOR and Marker beacon receivers? Marker beacon frequency is lower so i am unsure connecting it in with the VOR is a problem.

You cannot use a marker beacon antenna through this AV-571. Only nav and g/s signals.
