Replacing LNB

[BarneyBean]

Have an old Primestar oval dish, the LNB I believe has a short in it because it works for a while but then I'll loose the signal and picture and if I tap on it with a pen it comes back. Whats a good replacement LNB.

If you gut the casing on the LNB you get it will fit just fine in that grove. Its a 20mm groove. I use a Sadoun dual and have no issues.
