This illustrates how the performance of a 3 el 15m Yagi can be degraded by a
nearby 4 el 20m Yagi. The presence of the 204BA reduces the 15m forward gain
about 3 dB and degrades the F/B dramatically. Turning the 15m beam 90 deg
fixed the 15m problem, but then the boom of the 15m antenna interfered with the
204BA. Try removing the 204BA elements from this file to see what the naked
15-3CD can do.
