The UFO Shape Indoor Dual-Polarization Ceiling-Mounted Omnidirectional FPV Antenna is a compact, low-profile solution engineered for seamless indoor wireless coverage in drone racing venues, VR/AR training facilities, and multi-room FPV relay systems. Its distinctive saucer-shaped radome houses dual-polarized radiating elements that maintain stable link quality regardless of receiver orientation, eliminating signal dropouts caused by aircraft roll or pitch during high-speed maneuvers.
Designed specifically for ceiling installation, the antenna’s omnidirectional H-plane pattern ensures uniform 360° azimuth coverage across entire rooms or hallways without dead zones. The integrated N-Female jack provides a secure, tool-free connection to standard coaxial cables and video receivers, while the lightweight ABS+PC enclosure blends discreetly into commercial and residential ceilings.
Operating across the 5.8 GHz FPV band (5645–5945 MHz), this antenna supports both analog and digital video transmission protocols including DJI O3, Walksnail, and HDZero. Pre-certified with CE, FCC, and ROHS, it ships ready for immediate deployment—no additional lab testing required.

● Dual Circular Polarization — Simultaneous LHCP/RHCP reception maintains link integrity through aircraft banking, flipping, and multipath reflections common in indoor concrete environments, reducing video breakup by up to 70% vs. linear antennas.
● True 360° Ceiling Coverage — Saucer geometry positions phase centers optimally for downward-facing radiation, delivering consistent signal strength from wall to wall at typical 2.5–4m mounting heights without null zones directly below.
● Ultra-Low Profile Design — At just 38mm tall, the UFO form factor sits flush against ceilings, avoiding visual intrusion in retail spaces, studios, and homes while meeting ADA clearance requirements.
● Tool-Free N-Female Jack — Integrated panel-mount connector accepts standard N-male plugs without adapters or soldering, enabling field-swappable cable upgrades and simplifying maintenance in hard-to-reach ceiling locations.
● Flame-Retardant Enclosure — UL94 V-0 rated ABS+PC radome complies with commercial building fire codes, allowing unrestricted installation in schools, hospitals, and public venues where plastic antennas are otherwise prohibited.
● Pre-Certified Compliance — Ships with CE, FCC, and ROHS documentation, eliminating 4–8 weeks of independent EMC testing and accelerating project handover for system integrators.
● Indoor FPV Drone Racing Venues
● VR/AR Training & Simulation Centers
● Multi-Room Video Relay Systems
● Warehouse Inventory Drones
● Studio Live Production Cameras
● Smart Building IoT Sensor Networks

Q: How does dual polarization improve indoor FPV performance compared to single-pol antennas?
A: Indoor environments generate intense multipath reflections that scramble linear polarization. Dual circular polarization (LHCP+RHCP) captures both reflected and direct signals regardless of drone attitude, maintaining usable video through rolls, flips, and behind-wall passes. Field tests show 70% fewer frame drops versus linear alternatives in concrete buildings.
Q: What ceiling height range is this antenna optimized for?
A: The 60° vertical beamwidth delivers optimal ground-level coverage at 2.5–4m mounting heights. Below 2.5m, coverage area shrinks; above 4m, consider our 5dBi variant. We provide free placement calculators—email your room dimensions for a customized layout.
Q: Is the N-Female jack field-replaceable if damaged?
A: Yes. The jack uses a standardized panel-mount footprint compatible with off-the-shelf N-female replacements. No soldering required—simply unscrew the retaining nut and swap. Spare jacks included with bulk orders over 500 units.
Q: Can this antenna handle simultaneous analog and digital FPV systems?
A: Absolutely. The 5645–5945 MHz bandwidth covers all major analog channels plus DJI O3, Walksnail, and HDZero digital bands. Dual polarization works identically across protocols, allowing mixed-system events without antenna swaps.
Q: What’s the lead time and MOQ for custom color or connector?
A: Custom samples ship in 5–7 business days; production takes 15–20 days post-approval. MOQ is 100 units for any modification. Standard white/N-Female units ship within 48 hours from stock.
Q: Do you provide installation guides or radiation pattern files?
A: Yes. Every order includes PDF installation instructions, measured E/H-plane plots, and S-parameter Touchstone files. Our RF team also offers free venue-specific placement consultations to maximize coverage efficiency.
