[QUOTE="RimaNTSS, post: 995149, member: 312276"] I think that key-word here could be "X-pol", which is by the way one of the parameters of the performance of the dish. And antenna on Az/El mount will have greater X-pol effects, especially on inclined satellites (far-West and far-East). Polar-mounted (skewed) antenna will have better X-pol characteristics, therefore it will perform better. Will not argue anyway. Back to my idea to make CM dish skew-capable: made small frame from 20mm square tube to which welded 4 segments with holes in them. Of course, made a small mistake and with this frame will be able to skew antenna only 15* each side (was thinking about 30*) :oops:. Angle (step) between holes is 5*. Next time will do better. Now should think about elevation mechanism... I think 2 M10 threaded rods will do the job. [/QUOTE]
