INSTALLING MULTIPLE ANTENNAS:
When installing more than one wireless unit in the same location, it is important to make sure that great care is taken to insure that the radio frequencies (channels) are
properly spaced apart. For tower applications with two or three wireless master units in close proximity on the same pole, Videolarm recommends utilizing the manual
channel mode; antenna gain of 11dBi and mixed polarization between antennas. It is recommended that antennae maintain a minimum of 4 ft of physical separation and
are oriented with greater than 45° of angular separation. If 45° of angular separation cannot be met, then it is recommend a minimum of 12 ft of physical separation.
