Ok...  Andrew  heliax co sez to use silicone on coax connectors... to eliminate ... 'microscopic arcing'.

Ken at Cal-Av sez the same thing.   The silicone is to fill the voids..since u always end up with tiny
air pockets, even with connectors cranked tight.   

This is a silly question, but when did silicone start to conduct anything ??   [Dc/60hz/RF]  
'Conducto-lube'  which is grnd up silver powder in grease would probably work better,
but I would be leery of using conductive grease.. as it can bunch up at the bottom..
and cause an arc from base of pin, over to braid/shell. 

Conducto lube is made by 'cool-amp'   co in Ore. 

So what's the real story on silicone on coax connector's ??    If it is ok to use... is there
a certain type to obtain??    I think there is several different types of silicone.  Some
comes in a tube.  [ like toothpaste].. and some in spray bombs.   Seems to me the stuff
in tubes comes in a doz diff formulations... and some of em are NOT good for electrical
use.... like coax connectors. 

tnx.......... Jim  VE7RF
