So it works OK. I have the Dawn and Norsat LNBs attached to the Andrew orthomode feed assy, the feed bolted to the Channelmaster horn, and the outputs attached to an RCA
multiswitch.
And it works good-
PBS feeds at 75%, quality 68-70.
Montana PBS at 75%, quality 65-68
Even the IRDU muslim channels at 75%, quality 62-68
Don't go to this extreme unless you have the parts already- I spent $40 plus shipping for the feed (ebay) another $15 or so for the multiswitch, and already had the LNBs.
All this came about because I wanted 2 independent outputs off that dish, and finding a C120 flange dual output LNB (only
Invacom makes it) was getting hard.
But it works, even at the reduced voltages present at the LNBs.
