Hi Guys (Bob)



I've gone for the simple rod com antenna (http://www.aircraftspruce.com/catalog/avpages/stainlessantenna.php) having heard good reports (compared to the much more Comant types) the connection is a simple bolt - I presume PIDG connectors (both centre core and shield) keep them as short as possible, any other thoughts guys ?



Also: one more time - how close/distance from the transponder aerial should the two be ?



Regards

   That will work. Cessna produced thousands

   of airplanes with that 'style' vhf comm

   antenna.  Is this a metal airplane? If

   not, don't forget the radials.

   As far as practical . . . but I've seen

   installations as short as 12" apart

   where owners reported no observable

   effects.

Hi Bob

It's a Van's RV9a (all metal), so a decent mounting backing/plate will suffice - yes
