Description : If I have to move from one place to another, approximately 50 feet east to west, with an antenae on a trailer, how do I set the antenae to the new position? (WiFi Tower reception)?
Last Answer : answer:How far away is the tower? Do you know exactly where it is? You need a meter that can show the strength of the signal. As you aim the antenna you look for the strongest signal, that is where you lock it into place.
