Chris,
I emailed Bob on that very topic. Problem is there is not enough room or length. The RV wingtips stick out a ways from the metal wing. Some years ago I was in Florida on business for a couple weeks. Normal people go to bars. I got a set of hangar keys and finished my buddy's RV7 wingtips including the archer antenna. They would work on a Onex with the big tips I think. Gordon, I may go for cat whiskers under the aft fuse or on either side of the fuse. Stay tuned...

Could you put one whisker on each tail? Not sure I'd want to give up precious panel space for obsolete tech, but fill your boots.

John,
I had that thought on the drive home today. Was going to talk to one of my former co-workers about it. He was in avionics and is also a ham radio guy. To get the proper length we might have to run the whisker out the back of the fiberglass tip. Would look art deco sort of.

Whiskers trailing out the vader tips would be so retro.

I think the Bob Archer antenna wouldn't work so well in a sonex - the RV wingtips have a lot more fiberglass area than the relatively flat sonex tips (to lay out bob's jpole).

I am using the Bob Archer antenna in the right tip of the ruddervator on my Xenos. Seems to work very well. This is probably only useful info for Xenos builders, as the tips are large enough for the antenna. BTW, I installed my ELT antenna in the left tip. The only external antenna is for the transponder.

Cheers.................Frank
