TJRC 5.8GHz Gold-Plated Circularly Polarized Omnidirectional FPV Antenna 2.0 to 3.0dBi SMA Female for 5 Inch FPV Drone V

Gold Where It MattersMost FPV antennas hide their conductive elements inside opaque plastic You trust the spec sheet and hope the manufacturing matches The TJRC Gold Plated Circuit Antenna puts its engineering on full display The visible gold plated circuit traces aren t cosmetic gold offers superior conductivity and corrosion resistance compared to standard copper or silver plated elements Over hundreds of flights through humidity dew and temperature swings gold stays cleaner Cleaner conductors mean cleaner signal Laboratory Verified PerformanceThis isn t a trust us antenna Every key RF parameter is individually tested and published Frequency MHz Efficiency Gain dBi 515071 032 05525074 963 11535077 562 56545086 062 74555084 113 17565087 813 68575075 893 12585078 653 17At the 5650MHz sweet spot this antenna achieves 87 81 radiation efficiency with 3 68dBi gain numbers that embarrass antennas costing twice as much Across the entire 5150 5825MHz band efficiency stays above 70 and gain holds between 2 0 3 7dBi Wideband consistency means reliable performance whether you re on Raceband 1 or pushing the upper limits of the 5 8GHz band What Those Numbers Actually Mean ≤2 0 VSWR Low standing wave ratio means more of your VTX s power radiates into the air and less reflects back as heat Your 600mW VTX actually delivers something close to 600mW of airborne signal 70 80 Average Efficiency Converts the majority of input power into radiated RF energy Budget
