Consider a pair of 91XG antennas stacked horizontally 1.5 or 2.5 wavelengths apart. (about 3' or 4.9') The 91XG by itself will attenuate WCPO & WUPX by roughly 30 db. The stack would improve that to 50 db, which might be just enough. The next problem is how to use a preamp that is not overloaded by the strong local stations, including WCPO. The Tinlee CF-7 filter outdoor model is one solution. http://tinlee.com/bandpass_filters.php?active=1#CFAL The filter would be installed between the antenna and the preamp. A good preamp would be the Kitztech KT-200-COAX http://www.kitztech.com/
Whoah! Thanks a lot!
