My System: CM 3.0m @ 28.2 w PACE | Just out of curiosity, prime dishes are obviously round but with offset dishes, would there be any gain if dish AND lnb where skewed to the same degree ? Just curious ... as I now own a prime focus you know  )) [ which might not get 2D but it will make a great sunshade for the summer ... ] | ||

Imagine the mounting brackets you would have to use!!

My System: CM 3.0m @ 28.2 w PACE | If I thought I would get more signal by skweing he dish I'd bend the whole pole ... never mind the mounting brackets... It is hard living in the "fringe" It's abit like the quest of the Englishman for some sunshine and the lengths he will go to to get it...! | ||

My System: Technomate TM6800D & TM1000D+ receivers, Stab H-H90 motorised Triax 1m dish 42E to 30W. Fixed Orbital 1m on 26E, 2 x minidishes.DigitAlB movies. A Bigsat BS-S77CX and a Sky Dodgibox. |
Since the prime focus dish is perfectly round, I can't see it making a blind bit of difference, as the end effect would be exactly the same as you had before surely. On an offset dish, I would have thought there would be an effect, and skewing the whole dish is precisely what a motorised system does. Robbo | |||
