How close can two Garmin gps puck antennas be mounted that will not cause interference and have reliable signal source. GTN650 and 300XL radios.
 
I have 430 and 496 antennae mounted side-by-side under cowling and this has worked well for six years.
 
650 and 430 antennas mounted

within 6 inches, just forward of windscreen. 430 in non-was (G56 antenna) -- 2 years ops with no observed issues. Pics on email request.
