5.8G FPV Antenna Panel Pagoda Pro 9.4 dBi High Gain TX RX SMA Female with SMA Cable Adapter For FPV Racing Drone SpecificationsCenter frequency: 5.8 GHzBandwidth: 660 MHz (5.47 - 6.13 GHz)Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)Axial ratio: < 1.3Antenna gain: 9.4 dBiHalf power beam width: 55° (horizontal and vertical)Radiation efficiency: 83.5%The 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. Package list: 1 × Planar antenna (inner needle)
