[QUOTE="dxsat, post: 517031, member: 193607"] With the feedhorn will come two semi- circular plastic adaptors, place these towards the front of the feedhorn so that the whole assembly is seated some way back. This is essential in weak reception areas as the FD of the dish is slightly longer than that of the feedhorn, which is 0.6 The obvious choice, placing the rings in the middle or point of balance, is the wrong one. The LNB and feed will tend to fall backwards so the bolts of the holder on the dish arm will have to be pretty tight. Don't forget to set skew, and a further refinement is a rain shade made from transparent plastic (like a shade on a telescope) to keep raindrops off the feedhorn cover. Some say you can spray it with silicone to have the same effect. When it is correctly set up, this dish gives really good performance. Don't do what I did when I first set it up and mount the main arm upside down.. [/QUOTE]
