I have a 100ft tower on a bulding and about 8 ants. on it. i was going to hook up my scanner to the ants. and see how well they do. i was woundering if there is any like beacons that transmit continuously at diffrent locations so i can see how far out they are receiving. i am from connecticut . And is there anyway i could tell if the ants. are uhor vhf without climbing the tower? thanks
