Antenna if you have the Mark II carbon fiber tail and wet wings. We place ours in the top fuselage surface of the baggage compartment. You can get it out to an angle of approximately 90 degrees which I was told was adequate and you bid it in to follow the contour of the fuselage with the point of the "V" towards the tail. Cable runs aft from the "V" behind the hat rack door before running forward. We built a small box out of E Glass to fit over the connector and this fastens to the head lining with Velcro. All looks pretty neat and easy to get at if ever you had a problem. With regards to performance, I'm still waiting for my full permit and have been flying within 25 miles of our home airport in England but I've been picking up the local VFR with no problem at 2000 feet.

I have one nav. in the (old) kevlar tail and one in the wing, wired to the two Nav sets, and both work fine. At least, I have not been able to detect noticeable difference of sensitivity, and I have the extended wing tanks, so most of the antenna there is submerged. Remember "wet wing" does not mean wet like in wet water - Gasoline is not a dipole molecule like water, and hence not a conductive screen.
