I take the AGC signal at the receiver tuner. on my main installation (2m prime focus) the variation is related to the signal level. this signal decreases as it moves away from the ideal point. I have just done the same test with an offset of 90cm and I have a strange reaction: the level of the AGC signal remains at 100% close to the ideal pointing then the quality drops to 0 as it moves away but the AGC signal remains at 100% !!! I changed the LNB for an inverto but same result!</p></blockquote><p></p>
