Hollis Helms Questioned where to place the SA 007 Nav. 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 may have missed something in the beginning of this discussion, but why are you

avoiding putting the Nav antenna in the wing, as described in Lancair Supplement

#1 (Antennas)?. 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.
