I have a full Skyview system in an RV8 and the bottom of the plane doesn't have lots of space between antennas. Can I place the ADSB antenna close to the marker beacon antenna? They're both "receiving" a signal and not broadcasting...I think.
If you're talking about the ADS-B antenna for the SV-ADSB-470 traffic/weather, you should be OK. If you're talking about the transponder antenna (ADS-B Out), that's going to be less OK.
