Laser Precision. Not Hand-Soldered Guesswork.
Most micro FPV antennas are assembled by hand. Tiny inconsistencies in coil winding and solder joints mean two “identical” antennas can perform dramatically differently. The Happymodel Crown LDS is different. It’s manufactured using high-precision 3D laser direct structuring (LDS) metallization—a process borrowed from smartphone antenna manufacturing. Laser beams trace the exact radiating element onto a 3D substrate with micr0n-level accuracy. Every Crown antenna that leaves the factory performs identically to the last. No outliers. No “bad copy” in the batch.

0.68 Grams. Your Whoop Won’t Notice.
Weight is the enemy of tiny whoop performance. At just 0.68 grams (30mm version) and 0.78 grams (50mm version) , the Crown LDS adds less weight than a single plastic propeller screw. Mount it on a Mobula6, Mobula7, or any ultralight toothpick build—the flight characteristics won’t change. Your power-to-weight ratio stays intact. Your cornering stays sharp. Your antenna stops being the heaviest component on the board.

VSWR ≤1.5 at 5800MHz. More Signal. Less Heat.
A high VSWR (Voltage Standing Wave Ratio) means your VTX’s power is reflecting back into the board instead of radiating into the air. This wastes battery, generates heat, and can damage your transmitter over time. The Crown LDS achieves VSWR ≤1.5 at the critical 5800MHz center frequency. Translation: nearly all of your VTX’s output becomes actual airborne signal. Your 25mW whoop VTX performs closer to its rated power. Your range improves without increasing power draw.

Dual Polarization. Your Choice.
Available in both LHCP (Left-Hand Circular Polarization, grey wire) and RHCP (Right-Hand Circular Polarization, black wire) . Match your fleet’s polarization for maximum signal transfer. Mix polarizations between quads for cleaner multi-pilot sessions. Circular polarization naturally rejects multipath interference—critical for indoor whoop flying where signals b0unce off walls, furniture, and metal shelving.

Two Lengths. Every Frame.
– 30mm: Ultra-short for the tightest whoop canopies and AIO boards where every millimeter matters. Keeps the antenna safely within the prop guard perimeter.
– 50mm: Extended reach for frames where the VTX is buried deep or the antenna needs to clear a battery tray. Still ultralight. Still aerodynamic.

IPEX/U.FL Connector. Direct Fit.
Standard IPEX (U.FL compatible) connector plugs directly into Happymodel AIO flight controllers, Mobula series boards, and any micro VTX with an IPEX antenna port. No adapters. No soldering. No modifying your canopy to fit an SMA barrel. P0p off the old antenna. Press on the Crown. Fly.

50W Maximum Input. Future-Proof.
Rated for up to 50 watts of input power, this antenna handles far more than any whoop-class VTX can output. If you ever move it to a higher-power toothpick or micro long-range build, the Crown LDS won’t be the bottleneck.

Features
* 3D LASER DIRECT STRUCTURING (LDS): High-precision metallization process ensures batch-to-batch consistency. Every antenna performs identically. No hand-soldering variance.
* 0.68G ULTRALIGHT (30MM): One of the lightest circular-polarized 5.8GHz antennas available. Adds virtually zero weight to whoop and toothpick builds.
* VSWR ≤1.5 @ 5800MHZ: Excellent impedance matching. Maximum power transfer from VTX to air. Minimal signal reflection. Reduced VTX heating.
* 3.5DBI GAIN: Optimized for micro FPV range. Balanced gain profile maintains usable signal during aggressive acr0 and tight proximity flying.
* LHCP & RHCP OPTIONS: Grey wire (LHCP) or black wire (RPCP). Match your fleet or deliberately mix for interference rejection in multi-pilot sessions.
* 30MM & 50MM LENGTHS: Short for tight canopies. Extended for deep-frame routing. Both weigh under 0.8 grams.
* IPEX/U.FL CONNECTOR: Direct plug-and-play for Happymodel AIO boards, Mobula series, and any micro VTX with IPEX port.
* 50W MAX INPUT POWER: Handles far beyond whoop-class VTX output. Safe for future upgrades to higher-power builds.
* 5500-6000MHZ WIDE BAND: Full coverage of the 5.8GHz FPV band including Raceband and low-band frequencies.
