Ultrasonic welding technology is used to optimize the traditional snap-on or adhesive process, which is prone to problems such as antenna loosening or falling off The FPC+PCB process is used to make the antenna gain more consistent, thereby improving the performance and stability of the antenna The hexagonal shape makes it more reliable Futuristic and tough design Easy to use Frequency range: 5.3GHz-6GHz Maximum gain: 2.65dBi (5695MHz) Minimum gain: 2.06dBi (5362MHz) Average gain: 2.4dBi Maximum VSWR: 1.76 (5917MHz) Minimum VSWR: 1.46 (5621MHz) Average VSWR: 1.75 Maximum radiation efficiency: 86% (5436MHz) Minimum radiation efficiency: 76% (5917MHz) Average radiation efficiency: 83% Polarization: RHCP/LHCP Cross-polarization suppression: -25dB (Due to different batches, the printed words on the product will be different, which does not affect use) Colour:Black Material:FPC+PCB Type: A: 150MM right-hand rotation/B: 100MM left-hand rotation/C: 150MM left-hand rotation/D: 100MM right-hand rotation<br><br>Package Contents: 2x Antenna Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
