Hi guys I wonder if you can help. i have a multiple lnb setup on a 80cm dish. It was each lnb was aligned to Hotbird 13, astra 1 19.2 and astra 2b 28 with no signal issues. I have now just had my external walls insulated and during the course of it the work men removed my dish before putting it back up on the wall. initially I lost all my channels but since they had scaffolding up, I went up and tried realigning the dish and picked up some of the sky uk channels on the astra 2b and some channels on the astra 1. however I cant seem to pick up any signals on the hotbird. I now just want to realign to get maximum signal back on at least the uk channels, as signal strength while it is above 50 on some channels, its below 50 on other and I was wondering if there was a good channel to try and use to align by getting max strength on that channel. sorry if I have rambled on but any advice will be appreciated.
