Yes. So here's a true story. In the late 70's I installed a translator in Utica, NY. It retransmitted WNYT on channel 13 from Albany. There was also a channel 13 in Rochester, NY that was 14 degrees off the back of the antenna. The terrain toward Richester was more favorable than the terrain toward Albany. When testing reception with a 10 element yagi Albany was noisy and showed cochannel interference. When aimed at Rochester the audio was fine but the picture was not there. By ganging 4 yagis; two with horizontal stacking and two offset using stagger stacking, the picture from Albany was perfect.
