…Can someone please explain to me what these are for?
I’d like to point my dish to Hotbird so I tried it last Friday and I spend
The whole day without result and no signal quality at all.
Is there an easy way to position/align the dish?

Thanks in advance.

You may find that 88cm is a tad on the small size, a 1.2metre may be more appropriate.

Hi rolfw!
tnx so much for d rply.

i have also 1.6m old dish but it's rusty. does it affect?
Can i use any lnb on any dish?
and should i point the head of the lnb to the center of the dish or where?
and how far should be the distance of the lnb from the focal point of the dish?
does it depends on the diameter of the dish?
i have Atlantic bird (tfc) setup at 5W with 97cm dish
and arabsat at 26E with 83cm dish.
the technician set this up and i'd like to learn also that's
why i spend the whole friday aligning my dish to hotbird 13E.
help me please. :)

btw, i know this is not the right thread for this but...
do u happen to know how i can upgrade my receiver?
or where to find the software for it. because i didnt find
any reply on my post in the software category.
