Lived in Prague for a couple of years about 13 years ago and was lucky enough to be one of the only ones with sky... Thunder storm one night with high winds blew the dish out, so went to the roof with 2 bits of string, tied them to it, dropped them down, went back to lounge and tried to position in, guess what, didnt work...
Then tried going back and forth between the roof and my flat and moving the dish a bit at a time... Doh!
So went next door to neighbour who was about 95 and didnt speak english and I didnt speak czech that well but managed to communicate that I wanted her to sit there and wait for the picture to come on, whilst I was on the roof... And we would communicate via phone with me being on a mobile... (The Mobile was a UK one by the way...) so first attempt,
I go to roof, call my land line... Nothing... I get off roof, go down 6 flights of stairs (no lift) explain again that its me on the phone and she needs to answer it.. She thought it was for me...
To roof again. Call, No answer... back down... She had gone back to her flat...
To roof again. Call, No answer... Back down... Shes cleaning my kitchen!
To roof again, call, ANSWER... move dish slightly, I say OK? She say OK. Great I thought, run down stairs, get to flat, she has changed the channel to analog and her afternoon soap!!
Loads more to add here (Another 4 runs up and down stairs)... But! Eventually we managed to communicate and align it.....
Moral of the story... get the help of someone who knows what they are doing...
You think thats hard try setting a multi sat set up like i have from 42 degrees east to 45 degrees west and tracking the polar arc and picking up about 32 sat positions in between. Fixed dish? Phaahh peice of cake.
