Specification:

0.12 grams. RG137 low-loss cable. Direct plug-and-play for Mobula6, Mobula7, Freestyle HD, and ECO. The antenna that replaces your broken stock unit and disappears into your build.The Lightest Link in Your Signal ChainA whoop antenna has one job: get signal from the VTX into the air without weighing down a 20-gram aircraft. The Happymodel 5.8G RG137 Antenna does exactly that. At 0.12 grams—less than a fifth of a paperclip—it’s the definition of ‘installed and forgotten.’ Your Mobula won’t know it’s there. Your video feed will.RG137 Cable. Low Loss. High Flex.The choice of transmission line matters in micro builds. RG137 coaxial cable offers an optimal balance for whoop-class applications: lower signal loss than generic micro coax, a slim 0.8mm diameter that routes through the tightest canopies, and enough flexibility to survive repeated bending during battery swaps and crash recovery. It’s the same cable grade used on premium micro VTX combos—now available as a standalone replacement.3dBi Gain. Optimized for Proximity.With ≤3dBi gain across the 4900-5900MHz band, this antenna is tuned for the close-quarters chaos of indoor and backyard whoop flying. The broad radiation pattern forgives aggressive acr0. Signal holds when you’re inverted. Signal holds when you’re behind the couch. Signal holds when you’re three rooms away and pushing the limits of your 25mW AIO.Direct Replacement. Zero Modification.The standard IPEX/U.FL connector snaps directly onto Happymodel AIO flight controllers found in:* Mobula6 (all variants)* Mobula7 (all variants)* Mobula7 Freestyle HD* Mobula7 ECO* Any micro drone using IPEX/U.FL antenna interfaceNo soldering. No canopy trimming. No adapter boards. P0p off the damaged old antenna. Press on the new one. Total repair time: under 10 seconds.VSWR ≤2.5. Honest Specs.At ≤2.5 VSWR across the 5700-5900MHz range, this antenna delivers honest, predictable performance. It’s not claiming laboratory-grade precision—it’s claiming reliable, fit-for-purpose whoop operation at a price that makes sense for a consumable spare part. The 50 ohm impedance matches standard FPV system requirements. Your VTX sees the load it expects.42mm Length. Canopy Friendly.The 42mm overall length strikes a balance between signal clearance and canopy compatibility. Long enough to route cleanly away from the flight controller. Short enough to tuck under the stock Mobula canopy without awkward bends or exposed radiating elements.Features* 0.12G ULTRALIGHT: One of the lightest FPV antennas available. Adds zero perceptible weight to whoop and toothpick builds.* 3DBI GAIN / 4900-5900MHZ: Broad frequency coverage including full 5.8GHz FPV band. Optimized radiation pattern for proximity and indoor flying.* IPEX/U.FL CONNECTOR: Direct plug-and-play replacement for Happymodel Mobula6, Mobula7, Freestyle HD, ECO, and any micro VTX with IPEX port.* RG137 LOW-LOSS CABLE: 0.8mm diameter. Flexible. Durab1e. Better signal preservation than generic micro coax.* 42MM OPTIMIZED LENGTH: Fits under stock Mobula canopies. Clean routing without excess slack or tight bends.* VSWR ≤2.5 @ 5700-5900MHZ: Honest impedance matching for reliable whoop-class performance.* 10-SECOND INSTALLATION: No soldering. No tools. No modifications. Snap off. Snap 0n. Fly.* CONSUMABLE SPARE: Stock antennas
