I have the tv unit for the N1 (not sure what model at the moment.) It has a 4 diversity antenna on it though. Is there a booster out there to improve the signal. Right now its ok but I want to get it better than what is comming in now. I live about 30 miles from chicago and should be getting great reception but so far its meh at best. Thanks for any information.

Don't know about boosters, but how are the antenna mounted? Are the windows they're on tinted?

Yes the antenna's are on the back window, I have 20% tint on the window (5 years old so its faded quite a bit). I just thought that they may sell a signal booster for this.

Regardless of whether the tint is faded or not, it still has metal in it. Try moving the antennas to an untinted window. That may improve your reception a bit.
