EMAX Pagoda 2 Antenna 5.8G FPV Flat Panel SMA
EMAX Pagoda 2 Antenna 5.8G FPV Flat Panel SMA
SPECIFICATIONS
-
Center frequency: 5.8 GHz
-
Bandwidth: 500 MHz (5.55 – 6.05 GHz)
-
Matching: S11 < -20 dB, VSWR < 1.22 (at center frequency)
-
Axial ratio: < 1.3
-
Radiation efficiency: 95%
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.
