This meter could probably be purchased at a more reasonable price, but it does the job. As you peak the dish position, the sensitivity adjustment becomes VERY touchy, going from no indication to full-scale with the slightest tweak of the knob. For those who cannot adjust the dish while staring at a meter, this unit also has an auditory signal (tone) that varies in intensity to indicate progress. The meter dial is lighted, so at a glance you can see relative amplitude of the signal, especially nice if you are outside after dark trying to recover your system from a nasty wind storm!
