[QUOTE="guest poster, post: 577961, member: 262401"] you can have walls all round sheltering the dish.. so long as the angle up to the satellite is clear.. not as difficult with a prime focus.. you do lose on the joins.... another issue.. although there is one big join on the 2.4 CM...it's not a lot but it all adds up. you could put some ali tape or something over the join... but it might look awful.. btw.. both the 1.8 & 2.4 asc's are bigger in surface area than FS's... they are oval and their width is 1.8 / 2.4 but taller ... where as a prime focus is circular but the view by the lnb is considered the same (by some) in offset (it sees a circle of 1.8 or 2.4). I disagree to that as well as both the 1.8 & 2.4 (& 1.2 etc...) are all larger in catchment area that is reflected into the lnb. We measure diagonally always to calc surface area .. ..You need to compare apples with apples.... surface area v surface area.. Anyway, it's usually a price thing.. £170 v £2600-£3000+ etc... but if one was to choose a Fortec Star ... it has to be put together very accurately, very carefully so not to buckle it ... use the right lnb /feed horn ... ......and when it's 100% .... seriously strengthen it with some diy engineering.
