diameter, and grounded to protect against electrical discharge.
Note that when operating in the U-NI-1 band (5150-5250 MHz), the FCC requires operators to adhere to
the following EIRP limit above certain elevations: “Maximum e.i.r.p. above 30 degrees measured from the
horizon ≤ 125 mW (21 dBm)”.
󰜌EIRP must be under 21 dBm at all elevations angles above 30 degrees. If operating in U-NII-1 band, the
installer has to take into account the elevation angle of each particular installation and radiation patterns
of the antenna used to determine the maximum allowable transmit power.
For example, consider the antenna pattern shown below of the B5 antenna, and the 25 dBi antenna used
for the B5c. If this antenna was installed at 5 degrees downtilt, maximum antenna gain should be noted in
the radiation pattern, at angles 5 + 30 = 35 degrees. In this case, it is -1 dBi. EIRP = transmit power +
antenna gain < 21 dBm. Thus transmit power should be limited to 21 dBm – antenna gain = 21 dBm – (-1
dBi) = 22 dBm.
The parabolic antenna pattern below represents both vertical and horizontal planes.
