الوصف

Specification: Brand:Swiftflying Color: Red. Size: 90mm/70mm Material: FRP Head + Copper RPSMA Male Connector Weight: 11.56g Features: Light Weight, Extremely Durable, Smaller than current omni antennas. Nearly Perfect axial ratio, Smoother radiation pattern. Center frequency: 5.8 GHz; Axial ratio: < 1.3 Bandwidth: 500 MHz (5.55 - 6.05 GHz); Radiation efficiency: 95% Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency) Originally the radiation efficiency was listed as 92%, this was a mistake. These values are based on simulation, actual measurements are below (they are very similar). The center frequency may shift a bit between batches as a result of variations in the dielectric constant of FR4. Also, not all brands of FR4 have the same dielectric constant. Frequency shifts up to 100 MHz are normal. NOTE: We suggest you buy 2 pcs, one used on the Drone, the other one used on the Fat Shark Goggles. Package Included: 2x 5.8G Pagoda-2 Omni Antenna
