My very first post

my current setup is dual Bev LNB pointing to 91 and Cable going into a 3/4
Multiswitch to 3 receivers. I am thinking of getting a another Bev dual LNB pointing to 82 but I can't think of a way to make it work without losing cable. Will a 5/8 Multiswitch? I looked up the spec for a terk 58 Multiswitch but 2 of the inputs require a 22kHz tone for switching and I don't think a bev receivers can do this. Am I right?
