In a way that was what I suggested a few days ago did I not? But ignored by
the two gurus. Tom and Rich: do your fighting on a private channel. I am
tired reading all those quarrels of yours. Tnx de >Hans

>Lightning has been mentioned as a possible cause of arcs - yet almost

>dismissal should be quite so quick..

>I understand little about discharge from the atmosphere - but I have felt
>large enough voltage to shock me by simply touching a 30 foot wire antenna
>with no more than a dark cloud passing over. And, I built an scr operated
>burglar alarm years ago with a closed loop operating about 2 feet off the
>ground. It picked up enough energy from dark clouds that the alarm would
>fire every time a dark cloud passed overhead.

>So, the question is, when the amplifier is actuated and relay closed, is it
>possible that a static discharge returns down the antenna - and while not of
>sufficient voltage to blow a hole in your roof, might add to the existing
>voltage to create an arc which otherwise would not occur. Perhaps the rf
>choke that all good amps have installed from antenna to ground would address
>this and short all to ground. This might apply to dc - but the rf choke
>might appear as a high resistance to the static.

>Could this be one of the causes of the arcs?
