I went to Maplins and bought a "Satellite Finder".
http://www.maplin.co.uk/module.aspx?ModuleNo=48325&doy=11m12
The price is just under 10 GBPounds.
It is placed 'in-line' between the Satellite box and the LNB.
The unit is powered from the supply coming from the Satellite Box (which also feeds the LNB).
It has a (meaningless?) analogue scale (0 to 10) on an analogue meter. It has a potentiometer so that you can adjust the gain of the DC signal sent to the meter.
There are a couple of LEDs which light up. One is marked "22KHz" and the other "H/V". These light up when there is a 22KHz tone (from the box - Lo or Hi Band) and to indicate whether the box is sending the signal which changes the polarisation (Horizontal or Vertical) of the LNB respectively.
Inside the unit is a small speaker which emits a tone. This tone varies as the reading on the meter increases. It says nothing about the 'buzzer' in the advertising on the website.
There is a small backlight which is ample for reading the meter in difficult lighting.
I have tried it out.
I connected a short (1 m) coax from the unit to the LNB and the (long) cable from the box to the unit. On the box I selected a station I knew was OK (BBC World Service) and then went up the ladder. I set the pointer to mid scale (5) using the potentiometer. I 'sprang' (bent) the bracket holding the LNB very slightly one way and the other looking for an increase in the meter reading. I got one so I then moved the dish appropriately. I did both up and down as well as left and right. Then I tried rotating the LNB and got a further slight increase. I tried moving the LNB towards and away from the dish with practically no change in signal strength.
Back indoors I found that the on-screen signal had improved.
For 9.99 GBP I think this is a bargain which does the job.
