I'm trying to set up a Toroidal T-90 Dish my center LNB is at 101 and I'm locked into AMC4 101 with a strong signal. When I place my other LNB for 87 I lock on to that one and skew the dish. Know I have strong signals on two LNB's and haven't been able to lock onto different sats unless there close to the center lnb. I checked some of the pics on a t-90 and I see that the holders are facing either way but normally that the screw to lock down the lnb is on the backside does it matter?
yes it does matter. The screws to lock it are on the backside (so they are facing the big dish)...also when using multiple LNB's they go opposite their place in the sky...so if you look at pics in the below link (first pic) the closest LNB is 110 and the farthest away is 72..
the main issue here in the US is the 2 degree spacing so we have KU sats at
72,74,79,83,85,87,89,91,93,95,97,99,101,103,105,10 7.3,111.1,113,116.8,121,
123,127,129
The main core is between 72-103 and then picks up at 123. I have had up to I think 14 on there using some stacked LNB's that were real narrow but since have scaled back a smidge
