<snip> In keeping with the word "simple": a piece of hook up wire running to the base of the antenna is much simpler than trying to send DC on the coax, depending on how hard it would be to install this wire. You can still use the shield of the coax as the return connection. Rick N6RK <snip> That technique for me when I had a UHF pre-amp up at the antenna for ATV work. I used the coax shield as the DC return. 73 de Gene Smar AD3F _________________ Topband Reflector Archives - http://www.contesting.com/_topband
