I've just finished installing one of the Bob Archer/Sportcraft nav antennas in my -6A's right wingtip, but since my nav radio is a little while from being ready to try it out, I thought I'd double check my work as best I could. Using an ohmmeter, I was surprised to see that there was continuity between the two conductors in the BNC connection. Thinking that it was my wiring error, I removed the RG400 lead and was going to crimp on a new connector but noticed that the two locations where the center and ground portions of the coax attach to the antenna are electrically connected by the antenna themselves.

Does that make sense? Is this how it is supposed to work? Do I have any business building an airplane?

Don't worry

There's a big difference between DC and RF energy. What looks like a short to DC is NOT to higher frequencies. There is electrostatic and electromagnetic "magic" going on there.
