Let me elaborate...
Dish is typically installed on top of the shed. When an adjustement is needed, its a pain in the ass to climb up the ladder, pray I dont fall through the roof, make an adjustment, then go check the signal inside.
So I bought a tripod (25$), took the dish down and installed in on the tripod in the driveway. As I adjust, I can see the signal via the TV in the garage.
IE- Close the garage door, have a seat and drink a few while am blind scanning the arc.
The experience has paid off. During testing, I successfully got 103W (which I was never able to in 1.5 years, but took 5 minutes w/ the new SP1PLL lnb), 15w, 30w, 113w, 116w and 125w.
All the trial and error, I had the motor elevation off by 9 degrees since day 1.
Cheers, K
