My Location

ok guys after considering about this thoroughly im decided
to do away with my motor and get a multi lnb holder
the dish is a technomate 97cm (which also known as a triax)
ive got meself two more tm quad output lnb's,3 diseqc switches
and a triax multi lnb,i want to set it up to recieve 13e,19.2e and 28.2e
is they a tutorial to set the lnbs for the holder (i never got one when i got holder)
would 19.2e be in the middle of the holder ?? will the 13e be on the right of the 19.2e
and will the 28.2e be on the left of 19.2e

any info on how to set these up
much appreciated
 
Yes, looking at the front of your dish, 28.2° would be to the left, 13° to the right and 19.2° in the centre. The bar will end up being inclined slightly up on the left and down on the right (don't forget it mirrors the actual sat positions) I've used a Triax bar in my own multisat setup. See here :

I have to say I find the Triax bar very frustrating but then I currently have seven LNB's on that bar and it needed some modding to get the sort of slant I needed.
 
im hopeing to have ago this weekend (thats when its stops raining lol)
i will be setting it up on the strongest transponders

13e 11137H---- --27500 Bloomberg
19.2e 12226H ---27500 EuroNews
28.2e 10773H -----22000 BBC-1

are these still the strongest or have they changed
also i like to fine tune it into the weakest transponders
what are the weakest ones
 
Certainly the BBC TP's are very strong (99% SNR here) I've never thought about weak ones on either 19°E or 13°E. Without going through all of them on my receiver I wouldn't know. You probably won't get super performance from the offset LNB's. They should be good enough to give you a quite large rain margin, but don't expect 99% from all three.
 
NHK World on 13E @ 11137H - 27500 is a weak one on Hotbird, on 28E I would have a look at Tiny Pop on 11307V - 27500, not the weakest but nowt specialpower output wise.
