Anyone ever heard of a chaparral 3 c-band polarotor? It came on the dish I got... it had an old Hytek LNA with an external block filter. Is that chaparral feed any good? I took the LNA off and junked it. Wondering if the chaparral is worth keeping. I did take it apart and clean it. Took the chaparral cover off the skew motor and the manufacture date was December of 1984. An oldie.
