I get the usual static like any CB, that I squelch out. Maybe a little extra since the coax has to be run along the length of the engine bay.
The key, as the folks at Bell’s CB said is a very good shielded coax, a very good adjustable antenna, and then ensuring they are properly adjusted using an SWR meter. I ended up trying multiple combos of things to get my set up into the proper form but once I did it works well.
Email me if you want the specs for my build as both versions of the file (word or PDF) are to big to attach here
