[QUOTE="a33, post: 1160463, member: 332642"] A rough calculation [B][I]for London[/I][/B] gives multifeed rail skew -15 degrees (did you take that skew into account?), and multifeed distance 13-19E about 4 cm for a zone 2 dish (using these specs: [URL="https://www.satellites.co.uk/forums/threads/calculation-of-the-focal-length-of-an-offset-satellite-dish-antenna-revisited.177783/#post-1120938"]Just Sharing This - Calculation of the focal length of an offset satellite dish antenna, Revisited[/URL] ) So the 4 cm might only be reachable with 23mm neck LNBs. You might use a monoblock or triple LNB, but I guess the triple LNB is designed for about 80cm width dishes? So I don't know how it would fit a zone 2 dish.
