If the desired signal is a single channel, two antennas connected 180 degrees out of phase (or flip one upside down), where they are spaced an odd multiple wavelength from the desired source, and equadistant to the multi-frequency side source (if there is a specific noisy source), might do the trick. You might look into these antennas: http://simplicitytool.com/mu_series_uhf_quad_array.htm http://simplicitytool.com/log%20periodic%20arrays.htm -- |---------------------------------------/----------------------------------| | Phil Howard KA9WGN (ka9wgn.ham.org) / Do not send to the address below | | first name lower case at ipal.net / | |------------------------------------/-------------------------------------| |
