Budd, I gotta rake hay so Im not puttin much time or thought into this sooooooooooo

I think its what I experienced before n several other gents below thought. I had one of those antenna tuner switch boxes once but regardless how I trimmed it there was nooooo difference. The problem was without using and properly bonding n grounding the shield any all unshielded hook up wiring into or out of the box was acting as a stray antenna so allllllll frequencies were getting to the receiver n the tuner had no affect.

I bet yours is the same situation i.e. all that wire acts as its own antenna and it will unless the shield is bonded at both ends and the actual switch is inside a faraday shield i.e. a bonded metallic enclosure.

If an antenna is grounded out right where it connects to a receiver any signal strength should be shunted but if theres much unprotected unenclosed unshielded wire or anything lying around loose YOU HAVE AN ANTENNA

PS my best area is DC tractor electricity n charging n ignition and secondary AC power distribution but if you get into electronics or radio or RF Im pretty much "out to lunch" so take this for what you paid NOTHING lol My old buddy Gerald is a practicing engineer (Im long retired) so better listen to him n others also
