The 1055-378 from Southwest Antennas is a 4x4 MIMO Omnidirectional Antenna that operates from 4.4 to 5 GHz. This C-band antenna delivers a gain of 5.3 dBi and can handle an input power of up to 50 watts. It has a horizontal (AZ) beamwidth of 360 degrees, vertical (EL) beamwidth of 100 degrees, and a VSWR of less than 2:1. The antenna's four RF ports and 45-degree slant L/R cross-polarized design provides enhanced polarization and spatial diversity for attached radio systems, allowing them to maximize data throughput and overall link budget.
The antenna features an integrated flange base for secure mounting to an aircraft, helicopter, UAS, or other vehicles. The mechanical design of this product has been specifically engineered and reinforced to withstand the higher wind speeds and low-pressure environment while in flight. This IP67-rated antenna is available in a module that measures 3.9 (H) x 4.5 (D) inches with 4 x N-type female connectors. The antenna has been specifically designed for aircraft installation with multi-port MIMO and MANET tactical radio systems.
