Jammer Antenna Shock-absorbing drum spring appearance Omnidirectional fiberglass antenna Suitable for backpack countermeasure equipment and vehicle-mounted suitcase-type equipment
This antenna is designed for "shock resistance + omnidirectional communication", compatible with multi-scenario security and wireless communication devices.
Key Features
- Appearance & Structure: Features shock-absorbing drum spring sleeve, tube caps (35mm/28mm), tube diameters (25mm/32mm), and dimensions Φ25*900mm/Φ32*900mm. Core parts: embedded N-type connector, FRP tube, antenna sleeve, large copper oscillator.
- Key Params: All models: 100W power bearing, VSWR ≤1.5, 360° horizontal beamwidth (no coverage dead angles).
- Frequency Bands: Covers 2G/3G/4G/5G (n41/n77/n78/n79), GSM, CDMA, TDD-LTE, FDD-LTE; plus UAV (flight control/navigation/image transmission), GPS/Beidou/WLAN, Bluetooth, WIFI-2.4G/5.8G. Specific bands: 433M/900M/1.2G/1.4G/1.5G/2.4G/5.2G/5.8G, with gain 3±1dBi-10±1dBi and vertical beamwidth 9±3°-55±10°.
Core Advantages
- Strong Shock Resistance: Shock-absorbing sleeve reduces vibration damage (e.g., vehicle jolts), stabilizes performance in mobile devices (vehicle-mounted/backpack-type), extends service life.
- Stable Performance: Large copper oscillator + 25mm/32mm tubes (32mm for higher power/efficiency) enables long-distance transmission; VSWR ≤1.5 (low loss) + 360° coverage, reliable for base stations and emergency devices.
- Easy Installation & Compatibility: Embedded N-type connector for simple setup; 25mm/32mm tubes fit most security devices (backpack/suitcase-type); 8 frequency bands work with UAV remotes, walkie-talkies, GPS.
- Durable & Environmentally Adaptable: Outdoor FRP material resists temperature changes, humidity; double protection (copper oscillator + FRP tube) withstands collisions/rain, suitable for long-term outdoor/field use.
