Success! Sort of... I have a couple more questions below.
First, on the success. I ended up moving the CM4228HD to the bottom of the mast on my roof and 4 of the 5 major networks had acceptable reception (compared to 2 at the top of the mast). I then tied the balun to the mast moving it behind the dipoles as described at HDTVPrimer (
http://www.hdtvprimer.com/ANTENNAS/TemporaryPage.html) and now I get 5 of the 5 major networks! I am getting some pixelation on 2 of the networks. What can I do to squeeze a little more signal out of my system? In an early post John mentioned using a Winegard HDP269 preamp instead of the Winegard AP-8700 preamp I'm currently using. Would exchanging preamps improve my signal (about 45 feet of coax and no splitters)? Would replacing the coax previously used by DirecTV improve my signal? If so, what coax would you recommend?
