Reception of WBNS on channel 21 would require not only a large antenna array, but also additional rejection of WCPO on channel 22. WCPO is predicted to be 69.6 db stronger than WBNS. Another concern is WUPX, also on channel 21.
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.
