I have a Trav'ler on my motorhome, and a tip for you. Use switchable outlets for the 120VAC power to the receiver and also the Trav'ler. He will want to turn the Trav'ler on without the receiver being turned on so that the dish can locate and lock on to the satellites first. Then the receiver can be turned on. Otherwise, the receiver will complain that it is getting no signal. I found a switchable outlet at Amazon that I plugged into my power strip for the Genie. When I turn on the power strip, that powers up the Trav'ler. Then after it does its thing, I turn on the switchable outlet and that powers up the Genie.
