Question......I'm in the process of installing the doulbers for the Com antennas and going the typical conduit and alodine approach others have used under the rear seats. I made the hole in the bottom skin and doubler just large enough for the antenna connection to fit through. Do I need to make this slightly larger so in the future I can get the BNC (sp) connector through the bottom if I need to make a new connection? It will be trapped in there otherwise. Will this cause any problems with grounding?
This stuff is all new to me. Thanks for any help.

Absolutely! If you are going to have a connection in a closed area, you need to have the hole big enough to get the wire through, and leave plenty of slack to be able to replace the connector a couple of times if necessary. Without that hole, you won’t be able to install the antenna at all because you won’t be able to get the wire out of the hole to connect it to the antenna. You should be grounding fine through the screws, which I assume are going into nutplates.

This reminds me of one squawk I forgot to mention in my PIREP. I had a problem with the radio where others could hear me fine but I could not hear them. I could not even hear the chase plane unless it was within 20 feet of me. Originally I installed the cork gasket that came with the antenna in between the antenna base and the fuselage. i.e. grounding through the screws only. Once I took the gasket off grounding improved and I could hear people just fine.

Sean -FWIW, I made a couple inspection plates right over the antennae in the forward outer corners of the seat floors, and mounted them with angles riveted to the ribs and a homemade U-channel at the aft end of the doubler, riveted to the seat floor.
This makes it easy to get at the antennae, and helps immensely with running the wiring. I put a hole in the middle of the inspection plate with a large rubber grommet that was a slide fit on Van's conduit, and ran the conduit vertically there to and through the uppermost lightening hole immediately forward of the inspection plate. This allows the inspection plate to be slid up and out of the way when you need to get in there.
There is one conduit running under the baggage floors to the inspection plate/antenna area, and another that goes forward from there. This lets me push and pull on the big #2 cable, especially, thus expediting the threading of wires.
Hope this is of some use
