I have a 2m dish that I would like to put on my tower without destroying the pattern of 2 x 12 ele 144 MHz yagis. I have a feeling that having the dish at 90 deg to the yagis will be better. I wonder if the dish is offset from centre and then rotated about
the mast below the head unit this will be possible. I would support the lower part of the pole used to support the dish with a ring with slip bearings. This would allow me to get on 13cms as well.
