We have a different version of the TailGater (older model of something - 1000- looks just like TailGater) but it doesn't work very well, so we quit using it after a couple months. But it's pretty old.
We also see a 'dish looking' set up at Camping World (without the surround case, like TailGater $449) and it's MUCH less money $159). And seems to work outdoors as well, and is much smaller and easier to store. We travel in a truck camper, so space is a premium. BUT, don't want to sacrifice space for a poorly working antenna either - why pay less if it doesn't work well.
We don't want to 'be cheap', just get a good quality antenna without breaking the bank unnecessarily. We also have the cable that carries signal and 12v.
