Comm antenna placement from exhaust?

[Tomcat]

Alright, so I'm just finishing up all the wiring on my S-1, all I have left is to build a bundle for the comm which brings me to my question. I'm going to be mounting a Comant CI-122 or some sort of bent whip antenna on the belly, how far away from the exhaust does the antenna need to be to keep it from being damaged by heat or otherwise? Most I've seen are on the forward belly panel and that's where I planned on putting mine, but wasn't sure if exhaust from a 4-1 on the centerline would be an issue if the antenna was also on the center line? Does the antenna need to be on the center line of the airplane to have equal amounts of ground plane on each side of it?
