WNYT-18 is at 183 degrees true, WMFP is at 121. The difference is 62 degrees.
A half wavelength on channel 18 is 11.88 inches.
If you build two right angle extensions and position the top antenna more toward WMFP and the bottom antenna further from WMFP, there is a magic distance when WNYT will be in phase while WMFP is out of phase. That distance is 1/sine62 * 11.88 inches = 13.45 inches. Therefore boom two offsets of 6.7 inches, one left and one right of the mast, and you'd drop the signal strength of WMFP by 15-20 db while not changing the signal strength of the main beam on any frequency.
