5.8GHz Gold-Plated Circularly Polarized Omnidirectional FPV Antenna 2.0 to 3.0dBi SMA Female for 5 Inch FPV Drone VTX Transmitter - Blue / 1 pc / 60mm

Gold Where It Matters Most 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 Performance This isn't a "trust us" antenna. Every key RF parameter is individually tested and published:

At 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 antennas oftenn waste 40-50% as heat. The TJRC doesn't. * 50 Ohm Impedance: Perfectly matched to standard FPV systems. No impedance mismatch losses. * Circular Polarization: Naturally rejects multipath interference—fewer ghost images when flying near buildings, trees, or other reflective surfaces. Omnidirectional Coverage Pattern The included radiation pattern plots tell the story: clean, balanced coverage across 360 degrees of azimuth. No deep nulls. No bizarre lobes that drop your signal when banking hard. The E1 and E2 face plots confirm consistent circular polarization purity regardless of orientation—critical for acro pilots who spend as much time inverted as upright. Four Colors. One Tough Build. Choose Pink, White, Transparent, or Blue to match your build aesthetic. The 111 × 18.5 × 18.5mm form factor sits perfectly on 5-inch and larger frames without looking oversized or awkward. At 12 grams, it's light enough for performance builds while substantial enough to survive crashes. Rated for operation from -40°C to +75°C—it handles freezing mountain launches and scorching desert flights equally well. SMA Female – Direct VTX Connection Standard SMA Female (female thread, female pin) connector mates directly with the SMA Male output on most FPV transmitters. The included extension cable (100mm blue feed line) provides flexible mounting options for frames where direct VTX attachment isn't ideal. Route the antenna to the optimal position—rear, front, or vertical—without being constrained by VTX placement.
