I put the Trac-star on my coach at Parliament last month and so far, so good. I had an older KVH that was not supported by the factory any more and was pretty much out of options. It took the service guy at Parliament maybe 45 minutes to change out the antennae and the controller used the same single wire coax from the roof. Easy. Amazing thing, and I'm not making this up, was the new unit acquired 60% signal strength through the metal roof of the service bay. I was getting Direct TV inside the building! I didn't think that was possible.
At any rate, the new system is super quick to acquire and we never lost the signal all the way back home to Pensacola. The old system was constantly losing the signal and would have difficulty reacquiring. I didn't know how good it could be until I bought the Trac-star.
