Anyone know where to find a compatible LNB holder for an old BJ HomeSat dish? This dish has a round arm instead of square or rectangular arm like most dishes. Also the 2 support arms mount on the lnb holder as well. Or is there an adapter that can be added to change the end to accept current universal lnb holders? Would like to try and possibly use this dish for a small dish c-band project in the future. Has anyone tried this? Thanks!
