Use a medium sized flat screwdriver totighten the Hose Clamp to the pole. Attach a 6 mm2 (10 AWG) ground wire with a maximum length of 1 m (3.3 feet) to the grounding hole on the2.back of the B5c and a suitable grounding location on the tower or structure. The provided grounding screw isM5 x 6mm.

If operating in U-NII-1 band, theinstaller has to take into account the elevation angle of each particular installation and radiation patternsof 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 usedfor the B5c. If this antenna was installed at 5 degrees downtilt, maximum antenna gain should be noted inthe 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 – (-1dBi) = 22 dBm.The parabolic antenna pattern below represents both vertical and horizontal planes.
