I posted this to uk.tech.digital-tv but subsequently thought it might be of interest to other potential d-i-y satellite-TV 'ers here too.
Lidl started me off with their inexpensive kit, 79.99 complete with dish, which worked fine. Its weak point is the flimsy dish mounting bracket. The snag setting it up d-i-y was selecting a location for the dish that was not obscured by individual conifer trees, clear line of sight to the satellite being essential.
For anyone uncertain of a suitable location for a satellite dish, possibly because there are tall buildings or trees close by, the sun can provide a useful guide in the next couple of days. (Monday 11 & Tuesday 12)
Twice a year, spring and autumn, the arc of the sun across the sky is practically identical to the arc on which lie the positions of the geostationary communication satellites.
At the time of the eclipse (sun-out) for each satellite, sun and satellite are at the same position in the sky, so anywhere where the sunlight falls will have a clear view of the satellite and tree/building shadows will indicate adverse locations.
The table of sun-out times is found from here:
e.g. for Birmingham:
It may be useful to take some digital photos of possible locations at the times of eclipse of selected satellites as a record of the positions of tree/building shadows for future reference.
