My names Tom Saccio and I have a question about antennas. When my panel was built the Avionics shop ran RG 400 cable from the instrument panel. All of the antennas that I installed are RG 58. The leads coming from the panel are only about 3' long. My question is do I run the RG 58 to the panel and connect to the short RG 400 or can I add on to the RG 400 and connect them to the RG 58 in the rear of the plane as I would like to do. The RG 58 that I hooked up is long enough to reach the panel without additional connectors. Any responses to this question would be greatly appreciated. The plane that this is going in is a Seawind.
Thank you,
Tom Saccio

RG58 and RG400 can be used interchangeably in this application. RG400 is
slightly lower loss (more efficient) at higher frequency, and has better
thermal characteristics (only important when running it through the engine
compartment). If you already have enough RG58 to reach the panel, use
that. You can either remove the existing RG400 pieces or add couplings
to connect the RG58 to the RG400. The workmanship used in installing the
connectors is more important than having RG400 vs. RG58.
