Thanks for the ideas an a comm antenna. Jim, your recommendation looks like it would work but I'd have an installation problem (difficult access) with the large foil area. I stumbled upon a post on another web site that describes how to build an antenna without a ground plane. The antenna build instructions can be found at: http://chrusion.com/BJ7/InvVeeAntenna4ULs.pdf. I'm going to give this a try. If it works I'll install it in the airplane.

I'll post the results here.

Thanks,

Mike
