Satellites appear at 2 locations on my 12 ft Dish - How to fix this?

[jsattv]

Guys for almost all Satellites that I can currently find on my 12 foot mesh dish - especially the Ku Band ones, I can see Signalling in 2 locations, that is for example 74.0W (ONN), I have locked it in on count 744 on my VBox III at approx 62% Quality, but I can also go back to Count 732 and find 74.0W again - but with only 37% Quality?? Is this a calibration thing?? I have been reading the "How to point a satellite dish and use a spectrum analyzer" info recently at: http://www.satsig.net/spectrum-analyzer.htm , but when I got to the Section on - PEAKING UP, it is very hard to understand! That is swinging the Dish either side of 2 Points till you lose the Signal - then set it in the middle, is this what I should be doing? Any replies would be appreciated.

hi jsattv, your getting reception via the dish's side lobes? with that 12 ft dish you could probably get onn on either side of the main lobe. the main lobe has the most of the gain and the side lobes may be down 20-30 db or more but still bring in signals. yeah, its a crappy drawing but i hope it helps! so there's nothing to fix really, just save the settings where you get the maximun signal (the center of corse)

Bali, thanks a lot for the explanation and the drawing.
