Both will work fine looking thru fiberglass Just figure out a mount 

under side. Best way to prove it is to do it. That was my method.

I have 2 (two) satellite antennas mounted to the top of my RV-10 

cabin. On is for a WAAS GPS sensor and the Other is for an XM 

weather receiver.The cabin top is entirely made of fiberglass/epoxy 

composite. I've looked in vain for information as to whether or not 

groundplanes are required for these antennas, and if so what 

size/dimension. I would dearly appreciate any guidance and direction 

the list or it's Sponsor might provide.



Thanks

   Ground planes at 1.5 GHz are not terribly

   large in terms of real estate . . . and depending

   on the antenna's design, may not be necessary

   at all.



   What ever manner of shelf, fabricated from aluminum

   sheet and used to position the antennas at the

   top of the fuselage will no doubt prove to be

   adequate.
