I have d* with a proscan HD receiver. It is basically a dtc-100 all dressed up. I have the 18x24 eliptical dish with dual lnb's I want to add a 3rd lnb and also an antenna for local Hd broadcasts. I am in the Elk Grove area of Sacramento. I would like to know if anyone has added the clip on antenna the one that fastens right on the dish. If so does it receive all local broadcasts. 3-58. If this antenna is to weak what are you using. P.S. the lnb's run into my house where I have a 5x8 multiswitch. How do I get the local broadcast from my antenna through those same lines and then to the receiver. I believe I need to use diplexers but am not sure. If I cannot run it on the same lines do I need to run a seperate line. Thanks.
