With 13dBi radiation gain across the 4800-6000MHz frequency range, this spiral directional antenna dramatically extends your FPV range and penetration compared to standard omnidirectional antennas. Perfect for long-range flights, building penetration, and challenging RF environments where every decibel counts.\n\u003cb\u003e\nPrecision-Tuned RHCP Circular Polarisation: \u003c\/b\u003eRight-hand circular polarisation (RHCP) rejects multipath interference—the signal distortion caused when your video bounces off trees, buildings, and terrain. Combine with a matching RHCP transmitting antenna on your drone for maximum signal purity and consistent video quality from takeoff to landing.\n\u003cb\u003e\nIndustry-Leading VSWR 1.5 Across the Full 5.8GHz Band: \u003c\/b\u003eA low Voltage Standing Wave Ratio of 1.5 or better across 4900-6000MHz means nearly all transmitted power reaches your antenna, not reflected back into your VTX. Your 1W or 2W transmitter actually performs at full potential—no wasted power, no overheating, no signal loss at specific channels.\n\n\u003cb\u003e50W Maximum Input Power – Ready for Any VTX:\u003c\/b\u003e Built on premium 141 line cable with robust PCB radome construction, this antenna handles up to 50 watts of input power. Whether you run a 25mW whoop VTX or a 2W high-power long-range transmitter, this antenna operates cool and linear across the entire power range without saturation or degradation.\n\n\u003cb\u003eCompact 92×68mm Build, 30g Weight with SMA Connector:\u003c\/b\u003e Engineered for ground station and goggle mounting. The flat panel form factor with 92mm diameter slips easily into your FPV backpack. Standard SMA male connector with RP-SMA compatibility via adapter ensures plug-and-play connection to FPV goggles, external VRX modules, and ground station receivers. Rated for -40°C to 60°C operation and 60m\/s wind vel0city for all-weather reliability.\n\n\u003cb\u003eProduct Details\nFocus Your Signal. Dominate the Distance.\u003c\/b\u003e\nOmnidirectional antennas spray your VTX power in every direction—including straight into the ground and sky where no receiver exists. The 5.8GHz 13dBi Directional Antenna concentrates that energy into a focused beam, multiplying effective range and signal clarity. Mount it on your goggles, tripod, or ground station, aim it toward your drone, and experience FPV video that stays locked even when omnis would have long since dissolved into static.\n\n\u003cb\u003eWhy RHCP Circular Polarisation Matters\n\u003c\/b\u003eLinear antennas suffer significant signal loss when your drone banks, rolls, or pitches. Circular polarisation maintains signal integrity through every manoeuvre. RHCP on both transmit and receive sides creates a matched system that rejects reflected signals—the multipath ghosting that blurs your video feed when flying near buildings, through forests, or at busy race events.\n\n\u003cb\u003eThe VSWR Difference\n\u003c\/b\u003eCheap antennas 0ften advertise high gain figures while hiding poor VSWR numbers. A VSWR of 2.0 or higher means 10% or more of your transmitter power never makes it to the antenna. The 1.5 VSWR specification across the entire 4900-6000MHz band guarantees efficient power transfer on every channel, protecting your VTX and maximising actual radiated power. \u003cb\u003e\n\nSpecification:\u003c\/b\u003e\u003cbr\u003eProduct Name: Directional Antenna\u003cbr\u003eFrequency Range(MHz): 4800-6000\u003cbr\u003ePolarization: RHCP\u003cbr\u003eRadiation Gain(dBi): 13\u003cbr\u003eInput Impedance(Ω): 50\u003cbr\u003eVSWR(4900-6000MHz): 1.5\u003cbr\u003eMaximum Input Power(W): 50\u003cbr\u003eInput Connector Type: SMA\u003cbr\u003eDimensions-mm(Height\/Width\/Depth): 92*68\u003cbr\u003eMax Diameter(mm): 92\u003cbr\u003ePacking Size(mm): PE Bag\u003cbr\u003eCable: 141 Line\u003cbr\u003eAntenna Weight(SMA): 30g\u003cbr\u003eRadome Material: PCB\u003cbr\u003eRadome Color: Black\u003cbr\u003eOperating Temperature(°C): -40~60\u003cbr\u003eRated Wind Vel0city(m\/s): 60\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e1 x Directional Antenna\u003c\/p\u003e","brand":"ontproduct","offers":[{"title":"Default Title","offer_id":49121287766241,"sku":"BG-2054542","price":63.88,"currency_code":"HKD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/9317\/8849\/files\/fbfbbcf5-f564-40af-8174-7475fd286ffe.jpg?v=1789397319","url":"https:\/\/ontproduct.com\/products\/5-8ghz-13dbi-high-gain-directional-antenna-rhcp-sma-rp-sma-fpv-antenna-50w-max-input-vswr-1-5-for-fpv-drone-vtx-transmitter-rc-quadcopter-freestyle-long-range","provider":"OntProduct","version":"1.0","type":"link"}
