I was sooooo happy with my new Tailgater. It worked absolutely wonderful at home. I moved it all over the yard and practiced setting it up.
Then we went on our first trip. I was all excited about setting up the Tailgater, it's sooooo simple. And ... you guessed it .... NOTHING! ARRRR. I moved it, moved it, moved it and still nada! I could hear the motor running inside the cube, so I knew I was connected to the receiver! I even put the cube on the top of the camper, and we could hear the motor running through the vibrations in the roof. Still ... no actual signal connection! ARRR!
I called the Dish helpline and asked what was going on. They guy hung in there with me. He told me to unhook the coax from the trailer and hook directly into the receiver. Well, I was a little miffed, because it worked perfectly fine at home! But I did it anyway just to appease him.
Well, by golly it worked ... FIRST SHOT! OMG! I thanked him and we were on our merry way for the rest of the week. I did have the coax through the window though.
Next day it REALLY began to bother me why it did not work before, and then I figured it out! I'd switched to a shorter (store bought) coax cable that ran from the trailer wall (inside) to the receiver, and did not use the cable the Dish technician set up for me. I went out on a limb and switch the wire back, and it continued to run perfect!
I would have never thought in a million years that the wire I switched would cause failure.
Bottom line? It could be your coax cable causing signal loss.
Edit: FYI, I also have the aluminum 3 eye dish on a tripod and it worked perfectly fine with my original coax. So the wire can make a difference between the tripod dish and the Tailgater.
Good luck!
