[QUOTE="a33, post: 1011818, member: 332642"] [USER=329484]@st1[/USER] : Thanks for your input! Indeed, discussion and dialogue is what makes this forum (or any forum) instructive. :) However, following your reasoning here, I would arrive at the [B]complete opposite[/B] of your conclusion, which was: My conclusion would be (but I'm no expert, as you) that with multifeed reception on bigger dishes you have much less interference from neighbouring satellites [B]and so [U]better[/U] reception, precisely because the reason you gave[/B]: because the signal on the central/neigbouring LNB drops more quickly as you move aside from that LNB, than with a smaller dish. So the signal drop you mention would only be to the rays received from parallel to the dish main axis. The rays that come in from a small angle (from the 'by-rider satellite') have their own 'focal point', for which a bigger dish would still give a better reception, I would say. The statement/reasoning of [USER=176704]@jeallen01[/USER] I still cannot follow; I cannot remember I've seen it before... But thank you for trying to give me an explanation. Indeed, as I wrote before, I've usually seen the opposite advice: For multifeed reception, take a big dish, so that you can counteract the loss of dBs for the outer LNBs. greetz, A33 [/QUOTE]
