Omnidirectional antennas communicate in 360 degrees while the sector antennas cover slices of 90 degrees, 120 degrees or 180 degrees. Generally Omni’s are used in less densely populated areas and sectors are used in more heavily populated areas.
The omni-directional antenna systems offered by Laird Technologies are constructed of UV-stable fiberglass with all stainless steel brackets standard. They come standard with type N female bulkhead connectors with extra heavy duty nuts for optional standoff type mounting.

Tech Note: Horizontally Polarized (HPOL) antennas are useful in areas where there is a lot of interference. The HPOL technology offers very good interference rejection of VPOL signals.
