Hoping to put my transponder and ADSB antennas within a foot of each other. All equipment is from dynon. Your thoughts?

You need to separate the antennas by at least 5 feet according to every brand of ADS-B gear I've researched thus far.

Dynon's recommendation is 2 feet, just wondering if anyone has experience with installations closer than that, thanks.

I'm using 2 feet per Dynon's recommendation and it's working fine.

Just over 2 feet. Got my VFR transponder check done yesterday and works perfectly along with ADS-B (the other antenna in the picture).
