I agree, I have the Base version connected to 50ft. of RG8 on an outside ant. I have it rigged up to 12ft. of old roof rake, thats snow rake, for you southern people. Works great. Up here in the northeast, mtns are kind of a problem, so the marketed "up and out" design of the Super M makes sense to me. I have a RS discone which works ok too, but feel I am getting a better signal from far away places, maybe not as good for the close agencies though, but really hard to tell. Not cheap, but I think well worth it. I think the grade of Coax is probably more important, and if outside, weatherproofness.
