Razar antenna

I've been flirting with going that direction as well. My KS Sprinter has a fixed antenna and isn't worth a crap. I bought a portable one at WalMart last year to watch the series when we were camping. I just move it around until I get a good signal. Wish I had my old batwing from my old trailer worked very good. Have to get something like the Rayzar since the new one doesn't crank and the ceiling is too high to put a crank style in. Haven't seen too many opinions on this unit until now.
