Superior Performance
The KP Performance KP-3SX4-90 Sector Antenna combines four ports with dual ±45 slant polarization, high 17 dBi gain with a 90 degree beamwidth in a single enclosure with one mounting point.

The KP-3SX4-90 is a professional quality antenna designed primarily for 4x4 or 2x2 MIMO point-to-point or point-to-multipoint applications in the 3.5 GHz Citizens Broadband Radio Service (CBRS) frequency band. This antenna incorporates advanced low PIM, dual polarization technology that allows for the interoperability of one 4x4 radio or two 2x2 radios with multiple transmit and receive path.

The sector antenna is ideal for applications requiring 90 degree horizontal coverage over one or more sectors and with 4-sector frequency-reuse two (ABAB) channel planning. This antenna supports LTE deployments in the 3.3 - 3.8 GHz spectrum.

Rugged and Weatherproof
The 4-port sector antenna features a heavy-duty UV-resistant plastic radome for all-weather operation. The heavy-duty, powder-coated mounting brackets allows installation with pipe diameter from 1.25" to 3.5" and various degrees of incline for easy alignment. This sector antenna is built to withstand speeds of up to 100 mph and survive in a wide-range of challenging environments.
