On 22nd and 25th April I got dropped frames on Coronation Street or Emmerdale. I have 2 dishes, each connected to a different box as I use one for a backup in case 1 dish is knocked out of alignment. But they are both giving the same amount of dropped frames in the same locations in the videos. Is this a problem in the broadcasts or an alignment issue on my dishes?

Can anyone please give me an easy way to align the dishes myself rather than pay someone to do it? Thanks
