However please note that the XJ40 antenna goes up and down using pulsed earth signals from the original head unit. It will not go up and down using any other head unit.
LOL why on earth does it use that method?? What’s wrong with a good old fashioned switched earth not pulsed?
Is just the late model ‘40? Something has jogged my memory about reading this phenomenon before.
I could graft in an early antenna and use the same line. Keep it all stock and reversible is my preference. I have spares of both early and late antennas.
