[QUOTE="hexah, post: 885936, member: 333852"] One thing to remember about oval offset dishes is that they have to be set up with true vertical mounts and be sure they are on the perfect focal plane i.e. presented square on to the satellite. The oval dishes are offset and the satellite at its angle 'sees' a round dish but you can't and it is easy to introduce distortions when setting up. That and higher potential mechanical strength is why big dishes 1.4m to 3m and bigger tend to remain circular (as are the Jodrell Bank sized dishes) rather than oval offset. I suggest reading [B][COLOR=#336600]Huevos[/COLOR][/B] comments again, as he is right as usual (imho). [/QUOTE]
