aiming the T90
1. Put T90 together and tighten all nuts and screws except the ones that allow you to adjust the skew, azimuth, and
elevation. I would only attach the middle LNB and tighten it down as its final install. Don’t bother placing the other LNBs
yet.
2. Use your compass to get the dish in the approximate azimuth.
3. Leave the skew alone!
4. Attach the RG6 cable directly to the LNB and to the receiver directly with no switches in the circuit. Add your Satellite
Finder in the circuit there at the pole with you and connect to a Dish receiver. (You can use the DirecTV receiver as below
if you can’t find a Dish receiver. The Dish receiver tells you exactly which sat you are tuning. DirecTV receiver will ID
101, 110, and 119 only.)
5. Find the middle satellite. a. I had problems with the Satellite Finder bought off the net so be careful. If it seems to be
taking too long there may be a problem with the meter. Dish receivers, even those that aren’t hacked or subbed, will identify
any satellite with digital signals. It sure was nice to lock onto a satellite and know which one it was! DirecTV receivers
will let you identify 101, 110, and 119 by choosing 101 in the setup menu and using transponder 4 for 101, 28 for 110, and 22
for 119. Dish receiver will work best. b. Very slightly move the whole dish by grasping the bracket apparatus holding the
dish itself and rotating until you find a signal preferably on the Satellite Finder meter at the pole with you and then by a
friend watching the receiver in the house. (You can be independent and move a receiver and TV to the pole with you!) The
amounts necessary to find or lose a signal may be in millimeters. Since your elevation bolt is not tight yet you should tilt
the dish upward and downward as you twist the dish around. Remember millimeters in elevation and twisting around the pole
matters!
6. Find the satellite all the way to the left as you stand behind the dish. This is the LNB with the greatest “R” value. If
you have the middle LNB pegged and the skew is set right then the extreme LNBs should fall into place just by sliding them
along the rail. Be sure to slide any other LNBs between the middle and extreme LNB onto the rail before trying to find the
extreme LNB! Tighten this extreme one down part of the way.
7. Find the satellite all the way to the right as you stand behind the dish. This is the LNB with the greatest “L” value. If
you have the middle LNB pegged and the skew is set right then the extreme LNBs should fall into place just by sliding them
along the rail. Be sure to slide any other LNBs between the middle and extreme LNB onto the rail before trying to find the
extreme LNB! Tighten this extreme one down part of the way.
8. Slide the other LNBs up and down the rail between the extreme and middle LNB into place by using the Dish receiver and
Satellite Finder.
9. If the Left extreme LNB has a signal of 100 and the Right extreme LNB has a signal of 50 you need to adjust the skew. If
you change the skew you will then have to adjust the middle LNB again but remember this LNB is very close; you didn’t move it
much.
10. Now that all the LNBs are lined up connect all 4 LNBs to one of your 4x1 diseqc switch, connect the RG6 to the switch
and to the receiver then go inside and set up the ird.
11. When that is done go back outside and put the rest of your LNBs on the other switch and test that group.
12. Connect these 2 diseqc switches to the for example 0/22KZ and go back inside and set up the switches to work together
.
