A good analog meter is useful but not necessary. The look angle direction has to be completely clear. No telephone poles, etc. A word about the cable . Do not use extenders to lengthen your line run, unless the extended parts are completely under cover from any rain or moisture.
Most receivers have audio carriers for signal.
This will help get maximum signal without a meter. Tighten your mount bolts. The procedure for dish network is similiar to above explanation. If you are trying to setup a 500 dish with two lnbs, make sure that you require the local network feeds before attempting to setup this dual satellite scenario. No networks, use one lnbf and center the lnb in the middle of feed support assembly.
