Hi since moving in to the bungalow we have had problems receiving HD channels (via Freesat tv) they do that pixelisation thing.hasn’t been a problem just didn’t us hd channels until now because most main channels are now using hd as there main channels. ie channel 3 was itv but now is itv HD so now I need to solve the problem. So Here’s the questions 1 the dish looks old do I get someone to look at it possibly want to replace parts or is it just as economical to have them just replace the whole thing and be done with it. 2 how difficult would it be to set up if I installed it myself (have seen you can by complete kits inc satellite meter) 3 how much would average cost be to replace a satellite dish on a bungalow
