The days of amplifiers are over. We cover more than 70 miles along our Valley. We build microcells for small pockets of users that are too far to reach with normal antennas or have trees or hills, etc. Blasting more power is the way we used to do it, remember? Attitudes have to change and the first one that needs to change is that amps are good. They are evil and cause nothing but grief for yourself and anybody else wanting to use the spectrum.
