"So you're saying that an inverted V antenna gets/needs coax but a insulated backstay antenna must have only insulated wire?"Yes - an inverted vee is a tuned antenna with the feedpoint at the top of the v.I do not know what you mean by an internal tuner. Do you mean a manual tuner at your radio?Does the autopilot stop working altogether or just change course?Is the problem just since you changed tuners?What have you done to correct it? I would suggest shielding all of the cables and filtering the power source at the device(s).
