no sat signal recieved

[darin73]

hiya, long time no post,..well, still trying to recieve sky sat here behind the iron curtain. i have now a 2m 10cm dish atop a nine story flat building with nothing but cold clear russian sky,soo no obstructions. cable is not even 12 months ols, all co-ax connectors tight, dont have clue what LNB is??

the sputnik master claims the dish is positioned correctly..he brought i wee tv up to the roof and plugged co-ax directly into it, then put in the frequency 11.778 ( i think) ..but itwas the same frequency under the sky services menu..anyway he got two bars of signal...
strength 72%
quality 25%

but on my tv, under sky signal test screen, i still have nothing.
oh and the sky card should still be good as the bill gets paid monthly and other card still works in scotland.

i used the receiver head from my first 1.2meter dish which has 40mm diameter, when installing the 2meter dish..which had a bracket for 50 or 55 mm receiver head..does any one know if that would be the problem? maybe the head is too small for the bigger dish?

spacebo! (cheers m8z)

Did it show a transport stream number?

How long is the cable run approx?

Are both dish of the same type, i.e prime focus or offset?

If the LNB is for an offset dish, and both dishes are offset, it will work OK with the dish.

If bothe dishes are prime focus, and the feedhorn with the LNB is for a prime focus dish, it will work fine.

However, an LNB for an offset dish, won't work so well on a prime focus dish, and vice versa.
