My tailgater is really weird, and I havn't ffigured it out yet. At home, it works perfectluy fine. Tailgater to the satalite hookup in the camper. Hookuip to receiver. Receiver to television.
But when we are away fron hone, I can position the dish, but if it's connected through the satalite hookup jack on the outside of the camper, we don't get the signal. So, I use the wire directy from the tailgater to the receiver by putting the cable through the window. And then it works OK.
For the life of me, I can't figure out why is different away fron honme. I'm using the exact same cables, same rseceiver, same television. But I do get good reception eventually.
Don't know what the answer to your problem is, other than try the cable direct fron the tailgater to the receiver.
Edit: I've also discovered that if the tailgater is too close to the camper or too close to the truck, it won't position to find the satellites. It will only complete 2 of the 3 "check" steps. But, move it away farther and it then works. Makes me wonder how anyone can have one on the roof of their camper. I figure the metal in the camper and in the truck some how interfere with the positioning of the tailgater. (I don't know, I'm just guessing). I do know it has to be about 10 feet or more from both the camper and the truck, and of course an open SW sky.
