I am new to the forums, and am in a similar situation. I cannot run a second cable from the dish, and feel my only way around this is getting a Single Wire Multiswitch. Is this something I can install myself? Do I just run the 1 cable into it from the wall, and 2 out to the HR21 receiver? I looks huge to only have 1 cable in and 2 out.
Also, does DirecTV provide these if I call them?
Thanks in advance.
