I figured it out
Finished wiring for Portable satellite. I installed another wall plate with a jumper for "A" and "B". I also added a "C" for the #2 and #3 TV's.
I removed the park cable from the middle of the power booster. I attached that to "A" on the second wall plate. I ran a second short coax from cable on the power booster to "B" on the added wall plate. I made a small jumper for "A" and "B".
I added coax splitters to the coax for TV #2 and #3 and ran that to "C" on the added wall plate. I have the Dish 211k Satellite receiver which has Satellite out. I connect Sat out on the back of the Sat receiver to "C" on the added wall plate.
And the end result it that it all works (miracle). I may connect a AB switch but disconnecting the Jumper from "A" and connecting Sat In from the receiver is not a problem... if you could see around the corner TV 3 is also on
