Product Introduction

1.  Multi-band compatibility  : This antenna is capable of covering multiple frequency bands, which means that it can switch between multiple wireless communication standards, such as GSM, DCS, WCDMA, LTE, Wi-Fi, etc., thus improving the flexibility and versatility of the device.

2.  Wide applicability : Because it covers a wide frequency range from 900MHz to 2150MHz, this antenna is suitable for a variety of wireless communication devices, including mobile phones, routers, Internet of things devices, smart home systems, etc., greatly expanding its application field.

3. High efficiency  : Optimized design in multiple frequency bands enables the antenna to maintain high signal reception and transmission efficiency at different frequencies, which is essential to improve communication quality, enhance signal strength and reduce interference.

4.  Durability and reliability  : rubber sleeve antenna usually has good waterproof, dustproof and weather resistance, and can work stably in a variety of harsh environments, extending the service life of the equipment.

5.  Compact design  : In order to meet the installation needs of a variety of equipment, the rubber sleeve antenna is often designed to be more compact, easy to integrate into the equipment in a limited space, while maintaining good performance.

6.  Cost-effectiveness  : By integrating the functions of multiple frequency bands, the need for multiple independent antennas is reduced, the overall cost is reduced, and the design and manufacturing process of the equipment is simplified.

Application scenarios

  • Remote Monitoring Equipment: Weather-resistant solution for agricultural/environmental sensors.

  • Backup Communication Systems: Fail-safe antenna for emergency response devices.

  • Legacy Device Upgrades: Modernize 2G/3G equipment (POS terminals, alarms) without hardware changes.

 FAQ 

Q: Does this support 4G/LTE networks?
A: While it covers 2150MHz (used in some 3G systems), it doesn't support mainstream 4G bands like 700/2600MHz. Ideal for GSM/3G/IoT applications.


Q: Can I use it outdoors permanently?
A: Yes. Its IP-rated rubber housing and -40°C to +88°C range suit permanent outdoor installations.


Q: What devices accept SMA male connectors?
A: Compatible with industrial routers (Sierra Wireless, Teltonika), GPS trackers, IoT gateways, and cellular boosters with SMA female ports.


Q: Why choose 2.5dBi over higher-gain antennas?
A: 2.5dBi offers balanced omnidirectional coverage – ideal for devices in motion (vehicles) or dense urban areas where signal reflection matters.


Q: Is the antenna waterproof?
A: The rubber housing provides water resistance, but the SMA connector requires weatherproofing (dielectric grease/sealed enclosure) for heavy rain.


Q: Can I bend/damage the antenna during installation?
A: The flexible rubber design allows 90° bends but avoid sharp kinks. Withstands typical vibration/shocks in vehicles/machinery.


Q: ROHS compliance – why does it matter?
A: Ensures no hazardous materials (lead/cadmium) are used – mandatory for EU/NA sales and eco-conscious industries.


Q: How does <2.0 VSWR improve performance?
A: Minimizes reflected power (98%+ efficiency), reducing heat buildup and extending transmitter lifespan in continuous-use scenarios.
