So you would be using a CI-122 com antenna ? 

The CI-122 extends down about 19” from the belly of the airplane.  Tight but it will not drag along the tarmac.

I have a CI-122 on the belly of my Encore. It is there because when I had my Aspens installed the shop could not meet all the distance requirements on the top for all of the antennas and RSM's that I had. So they removed the rear com antenna from the roof and put the bent whip on the belly.

Makes sense . I had a CI-121 there once 

Loran .... There are some blogs saying you could use a slightly shortened CI-121 as a com

One more thing I forgot to mention earlier, because I forgot that Aviation radio is AM. AM transmitters can become over modulated if the input audio is adjusted too high. When they become over modulated they become very dirty and will bleed over on other frequencies. In this day and age I would expect the Garmin design to include some sort of limiters making this impossible, but I don't know one way or the other. I do know there is a Mic Gain adjustment in the Com Configuration page.
