i'll give you the answer: i don't have commertial tower, that is why the high power at the antenna, that is why the high gain from the antenna for receiving, that is why the line is 7/8 heliax foam 30 feet long, that is why a siclair antenna amplifier between the duplexer and the msf5000, now, my car has a 45watt remote installed spectra, modified to use 150 watt "C" class amplifier and receiving antenna separated from the transmitting antenna, that is why i am using 4 watt MTS2000 all over the city and that is why i ask questions here "how far" and am i in the ball park with the range of my setup
