Inclinometer
When you use the inclinometer the thread should dangle from the centre of the circle in the top left corner, like the red line which I have added to your photograph. The small circle has a cross. Thread the thread though at the exact centre and stabilise with sticky tape on the back.
I think you are peaked up on the wrong satellite, about 5 deg too low and to the right of your wanted satellite. Go 5 deg up and then to the left
===============
Antenna
For vertical receive polarisation the starting position is with the Universal LNB cable connector pointed directly downwards. In this image the feed support arm will be directly to the right hand side.
Now apply the +39.8 deg clockwise adjustment. the feed support arm comes down by an amount of 39.8 deg - more or less as shown.
I am not sure what will be the polarisation scale readling. I think it will start at -90 and go down to -50 ( 40 deg amount of movement).
Signal readings.
Small changes in the reading like 16- 17 - 18 - 19 suggest that the LNB is working. It will go up when you get near a satellite, or point at the sun or the ground or hand.
An increase to a maximum of 29 shows that you have found a powerful satellite. If your elevation is correct by measurement you are most likely on the correct satellite. If not, it will be only one satellite wrong along the orbit. Try up left or down right for the adjacent satellites either way. Try up left first since the 4 polarisation bolts (when slightly loose) allow the dish to sag slightly.
Once you are peaked up on 29 the problem is in the modem configuration, wrong polarisation, wrong satellite.
When you have peaked up on a 29, mark the az and el so that you can always get back to that satellite. The next satellites are either up left or down right in a diagonal line.
Best regards, Eric.
