We had a Tailgater that died. Stone cold dead. So rather than futz around we got the newest mostest bestest, an X2. And it was.
Fast forward a few years and not using it one summer. It turned out to be a bit balky. After chunking out the mud daubers tubes in the bottom it worked again. The sequence was to dig out the mud, hose out the area with tuner cleaner and then hose it out with silicon spray. That worked; it doesn't make grinding sounds any more.
A couple of months ago we got quite a few "no signal" error messages while the satelites were quite clearly right there with no trees in the way. I cleaned up the connections and made sure they were tight but still the errors occured. So I used a different coax and those errors completely disappeared. The offending coax appeared to be fine but wasn't. That's happened a couple of times over the years.
It's a nice durable unit. All it needs is a self-defense system against dogs. A nice little tazer maybe.
