That looks about right enough to get a Q Quality) reading, except skew maybe, once you have a Q reading, you can fine tune things. You will have to skew the lnbf for whatever satellite you're aiming for, which is just rotating the lnbf in its holder a certain degree. You can find out the skew setting on dishpointer.com. Skew is very important on small non-motorized dishes, if it's not set close to what it should be, you'll usually get nothing.
Once you get some sort of reading for Q, try fine tuning the skew and slowly moving the lnbf foward and back in its holder to get a better reading.
Your dish should have three bolts on the back of it that can be loosened and then the whole reflector rotates for skew adjustment, but it seems in my experience that I can get better signal by skewing the Lnbf. If you skew the lnbf, set the dish skew to 0 (think that's 90 degrees on the scale) if you set the skew by rotating the dish, then set the lnbf for 0 skew. I hope that makes sense to you, I'm not the best at explaining things.
