dodge thanks for the info. I had just looked at those two options. My winegard antenna was installed by DIRECTV and has been receiving its power via one of my sat receivers and diplexing it with the sat signal. This is causing me 771 headaches with DirecTV!!!! Now I want to do away with the diplexers and feed my antenna power with a different source. Like the links you so kindly provided! Thanks. I was under the impression that I needed 12-volts? Does it matter? I don't want to fry my antenna it works great! Thanks again for your advice and help!!
