I know this seems like an odd place to ask about antennas, but only 750s with Viking engines (and accompanying radiators) will have this problem: where do you place your ADS-B (echo UAT) monopole antenna and where do you place your transponder (GXT 327) monopole antenna?  We only have a flat bottom surface under the seats and it would seem like the radiator would interfere with the signals and there is hardly enough room for both antennas.

Don't know if this will help. It is a 650 but does have the Viking radiator.


 Yes, that helps! I appreciate it. Antenna placement may be so obvious that no one bothers to document that this placements has worked on airplanes that are flying.  It seems like the locations that close to the radiator and other protrusions would compromise the antennas, but apparently not.
