first of all i dont know if this it the right forum for this question? cant find anything relating to satellite tv in general, not sky or freeview, please move my post if nessesary.

my question:
does it make much of a difference which lnb i use on a 3.6m dish?  i have a 3.6m i want to use to get the australia beam on C1, so far no luck, im using a 11300 sharp lnb i pulled off an old sky dish.  so far the best i can get is 94% on the Aurora test channel, is there a special way of doing this?  other guys i have spoken to have said its possible and other people are doing it, i should get 100% on a nz beam using a 3.6m dish.  im assuming i might need some kind of high end lnb?

edit: forgot to mention its a solid aluminium dish not a mesh dish

Ideally an LNB designed for a prime focus dish should give the best result. The LNB can have a prime focus feedhorn integrated (Fuji SSI-T20) or alternatively a separate LNB http://www.norsat.com/_catalog... and feedhorn http://www.chaparral.net/produ... are examples.

The scalar rings are specifically designed for a prime focus dish although I have not tried myself for many years now on a prime focus for out of footprint signals on Ku band.

If you are in Auckland I can offer some assistance as I have the feeds and LNB necessary and am personally curious.
