this is wrong: the amplifier that i use is linear rated at 90 watts running digital multicarier...there are arround 20 amplifiers inside the site. pointing 120 degrees in a triangular pattern with 9 or more antennas like mine are emitting arround 2kw on one level only. the towers are two or three levels for different freqzs...there is big diesel generator in the site's yard that supplys the site in case of power outage.
