I am assuming you mean "Can I connect more than one tv to the same receiver?"
The answer would be depends on your receiver. If it has "TV OUT" that uses coax plug then yes put a splitter on that line out and then run coax to the TV's.
I here use a video-audio transmitter to transmit the output from my pansat to a bedroom wireless.
So my set up is like this: RCA plugs to big TV in the "TV room" the coax to a splitter, splitter runs it to a bedroom and to the wireless transmitter. So We can watch the Pansat on 3 tv's.
There are 3 outputs on most receivers.All 3 are live.You can hook each to a seperate tv. (1)coax tv out,(2)rca out,(3)svidio.You can split coax out with a splitter for as many tvs as you like.After 6 or so youll need a booster or the pics will get a little fuzzy.
IF out is for a sat signal to 2nd receiver but both cant be used at same the same time.
IF out allowes you to "STRING" a second receiver but only allows you to use one or the other.If you connect a second receiver to IF OUT you must turn off the first so you can command the lnbs from the second.You cant use IF OUT and operate 2 receivers at the same time.Thats what dual lnbs are for.
