Doubler for antenna grounding

[JDA_BTR]

I have the interior primed. Located and drilled three doubler plates. I was going to sand some paint off of the primed surface under the doubler. The doubler will also be riveted to the structure and the exterior is unpainted so the four rivets will ground it also.

Question: if I want to put some paste or other conductive agent between the doubler and the fuse what is inexpensive and effective. I imagine I might not even need it but curious.

No need to sand off the primer. Install it with nutplates so you can easily remove the antenna and the rivets will ground everything.

that's a very good idea didn't think of that. K1000-3 I presume

Most antennas use #8 screws. So K-1000-08 nutplates.

Of course.... but that won't work for the Delta-Pop antennas I was planning to use. The studs are already on the antenna..... But I get the idea. The doubler is riveted in the corners; and you don't think more is needed.

For an antenna with studs, add a star washer under the stud nut (between the doubler and nut on the inside of the fuselage).

YEP, Star washers are great for grounding the antenna.
