| Subject: | HF antenna issues |
Bob and all.
I'm trying to insulate an aircraft's wiring from the rfi/emi effects of an
HF antenna in a fibreglass Long-EZs wing. A counterpoise to the antenna wil
l lie in the opposite wing.
I had thought of using a grounded (?) copper conduit for all the wing wirin
g ... fuel tank capacitance gauge/strobe and navigation lighting/vhf nav-co
m cables, but with an output of 100W I am worried that the in-wing HF anten
na will set up a field that will still cause issues.
There is still the case of using a common ground for the existing wiring an
d the new radio causing problems.
Any thoughts on a suitable insulator or solution to this?
Many thanks.
Patrick Elliott.

Swapped antennas. Just changed the connections at the antennas, and was able to
transmit from the apron to an in flight aircraft over 25miles away! The twiggy
looking coat hanger style antenna under the fuselage works like a charm! The
handheld works fine on the antenna that the A200 didn't like. Still need to flight
test the final result, but all appears resolved....... Go figure!

Sorry . . . still out of town but here's an exemplar approach.

The relays need to be pretty hefty . . . like S704 from B&C. Back in the office
tomorrow night.
