dont know if a dish receiver would work with it.. they expect their own brand of switches (god only knows why they don't conform to disceq switches to lower their prices for equipment)..
Someone asks every couple of months, to use only one coax for both Dish and FTA.
The short answer is that it's just not practical.
Then, they sometimes want to negotiate -
"Well, what if I did A and B?"
I haven't heard a good idea yet, and I've tried to think up some. -
The Dish receivers expect full-time access to their birds.
Any non-Dish hardware or wiring would be ripped out if you ever had them make a service call - they can't troubleshoot nonstandard hookups!
etc...
