How do I hook up four 90 degree sector antennas on one tower?
Conventional thought says that there aren’t enough non-overlapping 2.4 GHz DSSS channels to put 4 channels on one tower. Usually, panel antennas with high F/B are selected, and channel 1 antennas are placed on opposite sides (e.g. North & South) and channel 11 antennas are also placed on opposite sides (e.g. East & West). If separate access-points are used for all 4 antennas, the isolation may need to be increased between antennas on the same channel by spacing them farther from the tower face or on opposite corners of a building. FHSS systems may use separate frequency sets on each panel without problems.
