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.
