[QUOTE="Sergei, post: 170172, member: 206010"] Thanks, I guess there is not standard on LBN arm shape then? May be someone knows size of the Triax's LBN arm off the top of their head? - it looks rectangular to me and may be mine is roughly the same... I was hoping to find this info on Triax site but it seems to be down? I tried Sirius today with one LBN i have and it appears signal is a bit weaker (hten hotbird) Question: by how much signal will be reduced using LBNs with say 6,8 or 14 degrees (say I want Sirius and Astra 19 degr East) separation. There must be a simple graph somewhere on the Web? E.g. aerial amplification (DB) by LBN offset in degrees.. - or something like this. I asked in the shop I bought receiver from and they say I may need a bigger dish if I use 2 LBNs. Or from experience - does using 2-3 LBNs require bigger dish generally? by how much? I only have an 85(88) cm dish. Ta Sergei. Glasgow. [/QUOTE]
