i believe you meant discovery and not discovert ??
Use kingofsat it lists everything for you
so that you do not need to be asking these very simple
solution questions anymore => https://en.kingofsat.net/find.php?question=Discovery
instead try 28 East 12382 H 27500
Discovery Channel this works much better i find and has a working EPG Too,So much better than the Discovery Channel Ireland which you are trying which has a very low signal .
if you have a motorized dish why not try 4.8E there is many different Discovery Channel variations in PowerVU there ??
Good luck : )
