OK im sure this has been brought up before but I am new here. Why is it that when Iinstall a H20 with a KA/KU dish I am only getting a signal strength of about 75-80 on the receiver, I get about around a 94 or 95 on my meter, if I take the line off the H20 and hook it up to a D11 it reads about 93, is there something im doing wrong or what? any help would be appreciated.
