I'm going to call soon to set up my HR20 install, and I know I'll be needing a multiswitch, and was wondering If I can trust whatever the installer brings, or should I buy my own ahead of time? I already but my own RG6 and run it from the dish to where my receiver is, so it doesn't get kinked, and it is one piece all the way. I've heard the Zinwell WB68 Multiswitch is good......is that what they normally use? Or, am I just in overkill mode? Thanks!
