Product Introduction

  1. Decent Gain for Long - range Communication:The GLSDS136F antenna offers a gain of 5.5dBi, which is useful for enhancing weak signals. This gain helps in extending the communication range, making it suitable for applications where long - distance signal transmission is required, such as in remote area communication or for connecting devices over large distances.

  2. Stable VSWR and Power Handling:With a VSWR of ≤1.5, the antenna ensures efficient power transfer and reduces signal reflection. It can handle a maximum input power of 50W, which makes it suitable for various power - hungry applications without sacrificing performance.

  3. Unique Connector for Easy Integration:Featuring a PL259 connector, the GLSDS136F is easy to connect to a wide range of devices. The PL259 connector is a common type, which allows for seamless integration into existing communication systems, whether they are amateur radio setups or industrial wireless devices.

  4. Durable Steel Construction:The antenna is made with a steel radome, which provides excellent durability. Steel protects the internal components from environmental factors like moisture, corrosion, and mechanical stress. This makes the GLSDS136F suitable for both indoor and outdoor use, even in harsh conditions.

  5. Wide Operating Temperature Range:Operating in a temperature range of - 40℃ to 80℃, the GLSDS136F can be used in different climates and environments. Whether it's in a cold outdoor setting or a hot industrial environment, the antenna can maintain its performance, ensuring reliable communication.

Application scenarios

  • Commercial Trucking – Ensures stable communication for logistics and long-haul transport.

  • Emergency Response Vehicles – Critical connectivity for police, fire trucks, and ambulances.

  • Fleet Management – Supports real-time GPS tracking and driver coordination.

  • Off-Road Adventures – Durable design withstands rugged terrains and harsh conditions.

  • Public Safety Networks – Reliable communication for security patrols and disaster teams.
