I installed this unit on my sisters mobile home, she's getting a great picture on the FEW Chanel's she is getting, however she can't get some local (CH 4) Chanel's.
INSTALL DAY- I took off dish and mounted the antenna to DTV's existing post and bracket, Where her direct TV was disconnected at the house a Black cable was still connected to a small box going to another one, then from there to another? Who knows maybe a feed to a space shuttle!? I figured she doesn't have DTV anymore so I disconnected that cable following it under the mobile connected to a spliter with two green ground wires on each side, I disconnected all those and ran the coaxel cable straight from the new antenna to my own spliter and then in to both TV cables.
QUESTION:DO I NEED THAT GROUND WIRE? SHOULD I KEEP THAT BLACK CABLE CONNECTED TO THE OLD BOX? Would it make a difference in pickng better reception and possabley getting those local stations? Thanks for any help, I'm a her little sister doing the best I can with the hel of you all :-)
