Coupling, Stacking, Joining two TV antennas
Ask your HD Stacker TV antenna question: I have a stacker, I am trying to talk a friend into one. He has a rotor but for some reason won't use it. Do you know if you can stack two or three stacker antennas in 120 degree angles without ghosting?
Coupling two HD Stacker antennas is pretty simple but to couple three gets a little complicated due to phasing issues. When coupling two antennas always keep the connection cable running from each antenna to the coupler the SAME length. I don't know what you have for a coupler the CC 7870 antenna coupler works good. When coupling two antennas it is best to amplify the signal out of the coupler using a preamplifier.
My set up recommendation is as follows. With each HD Stacker antenna properly aimed run a short coax cable (4 feet is good) from each antenna to the antenna coupler. Out of the coupler run a short cable directly to the preamplifier. Connect the down lead cable that runs into the house to the preamplifier output. The down lead cable out of the preamplifier will carry the TV signals from both antennas. The Winegard LNA 200 preamplifier is a good choice when supplying 1 - 4 TVs. If there will be more than 4 up to 8 TVs in the system use the Channel Master 7777 preamplifier.
