This factory-priced multi-band omnidirectional sucker antenna integrates 433MHz, 2.4GHz, and 5.8GHz operation into a single compact unit with integrated 3-meter low-loss coaxial cable and standard SMA male connector, purpose-built for UAV telemetry, video transmission, and ground control station applications. The magnetic base enables instant tool-free mounting on metal surfaces while maintaining stable electrical performance across all three critical drone communication bands without requiring separate antennas or adapters.
Engineered for outdoor field deployment, this antenna features UV-resistant housing and IP65-rated sealing to withstand rain, dust, and temperature extremes encountered in agricultural, industrial, and tactical UAV operations. The true omnidirectional radiation pattern ensures consistent 360° coverage during dynamic flight maneuvers, while the pre-attached 3m cable eliminates connection points that degrade signal integrity in vibration-prone mobile installations. Direct factory pricing and bulk availability make it ideal for fleet deployments and system integrator kits.
As a certified manufacturer serving UAV OEMs and defense contractors in over 80 countries, we offer full customization including cable length adjustments, connector type changes (SMA/N/TNC), frequency retuning, and private labeling. All units undergo individual VSWR testing before shipment, backed by ISO 9001 processes and rapid prototype turnaround of 5–7 business days for custom configurations.

Why combine 433MHz, 2.4GHz, and 5.8GHz in a single antenna instead of using separate units?
Integrating three bands reduces installation complexity, weight, and potential failure points in mobile UAV ground stations. While dedicated single-band antennas may offer marginally higher gain, our tri-band design maintains VSWR <1.5:1 across all frequencies—sufficient for most COTS drone links—while saving setup time and eliminating cable management issues critical in field deployments.
Is the magnetic base strong enough for high-vibration environments like moving vehicles?
Yes, the neodymium magnet array provides >8kg holding force, validated per MIL-STD-810G Method 514.6 vibration testing for wheeled and tracked vehicles. For extreme shock environments (e.g., helicopter mounts), we recommend the optional threaded adapter for permanent mechanical fastening. Both mounting methods maintain electrical grounding essential for optimal radiation efficiency.
How does the 3m integrated cable affect signal loss compared to shorter cables?
Our low-loss RG58-equivalent cable exhibits <0.8dB/m attenuation at 2.4GHz and <1.2dB/m at 5.8GHz, resulting in <2.4dB total loss at 5.8GHz over 3m—acceptable for most UAV links where receiver sensitivity exceeds -90dBm. For ultra-long-range applications, we offer optional LMR-240 or semi-rigid cable upgrades reducing loss by 40%. Specify your link budget requirements for tailored recommendations.
Can this antenna be used onboard the UAV itself?
While electrically compatible, the magnetic base and 3m cable are optimized for ground/mobile use. For airborne installation, we recommend our lightweight fiberglass whip or patch antennas in the same tri-band configuration with direct PCB-mount connectors. Contact us for UAV-specific variants weighing <30g with aerodynamic profiles.
What quality assurance validates each antenna’s tri-band performance?
Every unit undergoes individual VSWR sweep across all three bands using calibrated VNAs, with automated pass/fail gating at ≤1.5:1. Sample units per batch receive anechoic chamber pattern/gain verification and cable assembly continuity/loss testing. Serialized test data is retained for 10 years and provided upon request. Mechanical validation includes pull-test on SMA connector and magnetic base adhesion verification.
How quickly can I get customized versions for my UAV program timeline?
Standard tri-band SMA units ship as samples within 3 business days. Custom variants (cable length, connector, retuned bands) deliver functional prototypes in 5–7 business days after spec sign-off. Our dedicated UAV prototyping line prioritizes urgent programs, and we maintain strategic component inventory to avoid delays. NDA-protected technical consultations available within 24 hours.
Available for OEM/ODM customization. Full VSWR plots and integration guides provided upon request.
