When putting the Com and Transponder antenna on the belly of a metal plane 

is there a distance that they should be apart?? Thanks Dale

   They're not terribly antagonistic to each other. Get the

   widest practical spacing but don't bust yer buns over it.

Here's the latest word I received from Comant...



"Standard separation for antennas is 36 inches.  This is especially true

for transmitters like VHF and Transponder.  The transponder is a

continuous high power pulse.  If space is an issue non transmitters may

have to violate this rule of thumb.



In other words, 36 inches in all cases - if unable to achieve this, make

sure the no antennas are within 36 inches of a transmitting antenna."



Hope this is useful...

I assume you meant the VHF and XPDR antennas should be "at least" 36 inches 

apart and not "exactly" 36 inches apart?

Good Evening Rodney,   

 The Comant antenna folks in their installation instructions specify a  minimum of 36 inches IF possible.

  

 Further apart IS better. But, closer will USUALLY work!
