I have a 75CM Eliptical DIsh with three LNB. I have the LNB hooked up to a
Multiswitch 4 x 4. I correctly positioned the dish to the right elevation and azimuth. I tested the with and without the Multiswitch. The picture quality is ok however I get a bit of snow or sparklies. I don't suspect microwave interference. Does anyone know what I can do.
