I picked up an old Muzak fiberglass dish. So today I decided to put it back on 103W Ku but both polarities, not just vertical for Muzak. I pulled the polarity plug in the feed horn and ground it out to accept both polarities. I put an old "Soup can" dual polarity ku LNB on the feed and mounted a Zinwell 3X4 multiswitch on the back of the dish to handle distribution. The Muzak mount is kind of unique. Not a pipe clamp mount like most. The dish I got came with a NPRM mast. Fortunately it's a standard pipe size and I had a piece to make a new mast. A little paint and a few zipties, I have a clean install and the dish works good
