ANTENNA GAIN
Antenna gain is a measure of the relative distance antenna can transmit a
signal. Gain is expressed in dB units and for every 6dB increase in gain,
transmission distance doubles. Accordingly, for every 6dB loss in gain, transmission
distance is reduced in half. The performance of an antenna in a given direction
is expressed in terms of Effective Isotropic Radiated Power (EIRP) and is
limited to 36dB in compliance with FCC regulations. The EIRP is a function
of radio Transmitter power, antenna gain and antenna cabling/connector losses:
