Rubber mats or aluminium strips ,or both. Sometimes one or two. Not always on the same place on the dish. Different dishes, different results.But all prime focus and I wonder if it's just Cyprus
I don't think it's just interference from BADR. Could be local interference from tv/radio/mobile phone transmitters. Like I said before ,the channels are still there but weaker and so the interference is "swamping" whatever signal we have left.
I did another one today and got 12.110H sky sports 1,2,3 back but not 12.152H sky sports news/eurosport2, I ran out of time but will try again. It's not guess work either,you need a quality sat meter with fast response because one inch either way and you "lose" the signal. Then if you fix one you lose another. You should see what else we have tried on the dishes :-)
I might try and post a photo later.
