You can easily do this as I have done it for 3 years or more with a dish 500 , then a dish 1000 and now with a dish 1000.2 . IF you have the lnbs plugged into the IN port on the terk 44 antenna , and you have the coaxes already run to the different receivers in your house from the OUT port on the antenna , then it is a simple matter of putting diplexors on each coax cable inside of your house.
Put the diplexor on the coax behind the receiver and then run the TV side of the diplexor to your antenna port or a splitter that runs to your antenna ports on your tv and your 622 receiver , vcr etc. From the SAT side of the diplexor you run the coax to the dishpro seperator that will split your sat cable into two cables for the two sat inports.
Remember the diplexor goes onto the coax cable coming in to your house FIRST then you can run it to the seperator and to the antenna port on your receiver or to a splitter that can be split to the various antenna devices: vcr, tv, dvd recorder, sat receiver.
The terk 44 is the easiest way to get sat and antenna on the same coaxes without putting up a big aireal antenna if you are within 35 miles from the broadcast towers.
