Is it  possible to use a multimeter connected to the LNB to point a dish to a satellite in case that you donīt have another way to monitor the sat signal? If yes, How do you connect the multimeter?
Thanks

You need a DC supply of 13 or 19 volts plus a noise power meter.   A noise power meter will show an indication at every satellite you pass.

Suitable very cheap 'satellite meters' are available.  Note that DC power from a satellite TV receiver or VSAT modem is also required.

To identify the wanted satellite you need a receiver that will recognise a known carrier. For example expensive satellite identifier meter, satellite TV receiver or VSAT modem, or a spectrum analyser and a knowledge of what carriers are on what satellites.

A typical VSAT modem behaves as a noise power meter until the wanted carrier is found, it then shows wanted signal quality.

To find the satellite, set polarisation and beam elevation, then swing boldly in azimuth to find the satellite.  If you find the wrong one try the next satellites either side along the orbit.

See dish pointing angles for Iraq to see how the LNB polarisation angle should look.  This map starts in Iraq but you may go anywhere by reducing the scale till you can see your country and eventually find your house !

Best regards, Eric.

Eric, itīs very difficult to obtain a noise meter nor satellite meter down here, thatīs why I want to know if I could use a digital voltmeter in order to measure kind of sat signal strength. I have a iDirect 3000 series satellite router and a 1.2 m patriot dish.
Thank you for your helpfull input.
