I need some sort of device to accurately point the dish towards the

work for digital.
Some sort of rapid reaction meter is needed inline between the lnb and RX.
I could make one if I had a suitable cct. I do not have a spectrum analyizer
for the ghz freqs otherwise that would be the answer.

When aligning my dish, I bought a small box, which you insert between
the LNB and the cable,
no need for batteries, as it takes power from the LNB supply voltage. It
has a needle meter,
and a buzzer with a sensitivity control. You first aim the dish with a
couple of degrees of
accuracy, then do a fine positioning either looking at the needle or
listening to the buzzing tone.
It has a very sharp maximum when the disk alignment is optimal, i.e. the
signal strength is peaking.
The price was reasonable, if memory serves it was around 20 Euro.
