This is interesting. I have an install (another try!) set for Thursday morning. They'll be doing a similar setup: 110/119 plus 61.5 to a single 942, but I believe instead of a switch they are going to apparently tie in the 61.5 to a DishPro Plus Twin LNB.
Question:
I already have two lines from attic to living room. I was planning on using one of them for an OTA (big channelmaster in the attic, with an amp up there already) and the other for the TV2 output of the 942. I thought I might then run two more lines in from the dish to the 942 for a total of four total lines into the living room (OTA, TV2 out, 2 satellite).
Would it be possible instead to run a single line from the LNB to the attic, use a diplexor to combine the OTA with the satellite feed and run that down a single line to the living room, split out the OTA to the 942 and then split the satellite feed to the two Sat tuners? That would mean I'd be running everything in on one line and could still use the second one for TV2 out.
If this will work without too much signal degradation then I'll be very happy and it would save on running extra cable!
CDH.
PS -- I should add that the OTA was running through a diplexor on my Voom set-up with no problems receiving locals.
