Sounds good. I have what's probably a similar one in my attic and it works really well. I had to move it to a fiberboard gable side after I had a metal roof installed, actually works better than when the previous owner had it pointing through the cedar shingle roof (rain); I think they were being cheap with cable as it had flat lead that was barely long enough, I never could rotate it exactly where it needed to be either the cable was so tight. With the relo I changed to coax adapter at the antenna and coax.
I used this site, nice graph and can tune for trees, height, etc.: http://www.antennaweb.org/default.aspx
I'll have to check out that TVfool sometime.
