I have a random wire on glass insulators of all in about 300' outside and the highest point is i guess 55'.
I have in the garage a hallicrafters S-38d, inside the house i have a Philco 46-1226.
Hallicrafters has A1, A2 & G terminations and there is an S shaped link bonding A2 & G together.
On the Philco i think dad used a wire to bond #2 and #3 together but i took that out cause the wire was corroded a tad.,, i did not put it back and i get good reception.
so.... to yesterday.................
I run a wire out from the Philco out to my existing random antenna wire. While touching the outside antenna im getting shocked.
- the hallicrafters is plugged into the outlet and is in the off position and is tied to my outside antenna during the time i am getting shocked. I isolate the hallicrafters from the outside antenna then verify the source of my getting shocked is from the hallicrafters,, and not the outside antenna. Confirmed YES the source is from the Hallicrafters.
The shock i get is more like a low voltage "sting" so to speak.,,
I look on the back of the hallicrafters and the S jumper is bonding A2 and G together.
I remove undo the S jumper , reconnect the outside antenna and the power up the hallicrafters and verify that i still have all good reception on bands 1 through 5.
I go back out to tie the philco to the outside antenna and no more stay voltage... and all is well for two radios tied to the same antenna.
What the heck is going on when a radio has A2 & G bonded,, it seems there is an injection of voltage on the antenna when a jumper is installed yet the Hallicrafters was in the off powerd down state.
do i stand a chance of putting both my radios at risk by not having the jumper?
I like the idea of having one antenna available for rado use no matter how many radios i have.
