Product Introduction
Precise UHF Band Coverage (400-470MHz)
The GL400S18 is specifically designed for the UHF band, covering 400-470MHz, ensuring stable and clear communication signals within this frequency range. It is particularly suitable for commercial walkie-talkies, professional dispatching, and outdoor operations.
Superior Impedance Matching, VSWR < 1.5
With a voltage standing wave ratio strictly controlled below 1.5, it achieves efficient energy transmission, reduces signal reflection and loss, and guarantees call quality, maintaining excellent performance even in complex electromagnetic environments.
2 dBi Gain, Enhanced Signal Coverage
Although a handheld antenna, it still provides 2 dBi gain, effectively enhancing signal transmission and reception capabilities, helping users maintain stable communication in densely built-up or remote areas.
SMA-K Interface, Compatible with Mainstream Equipment
Equipped with an SMA-K (male) interface, it is compatible with various brands and models of walkie-talkies and handheld radios. Installation is simple, the connection is secure, and it is suitable for frequent plugging and unplugging scenarios.
Lightweight design, weighing only 14 grams and measuring 180mm in length.
While ensuring performance, the antenna weighs only 14 grams and is 180mm long, balancing handheld comfort and portability, making it ideal for extended outdoor or mobile use.
Application Scenarios
Commercial and Industrial Communication: Used in construction sites, warehouse management, shopping mall security, etc., for efficient team collaboration when paired with handheld walkie-talkies.
Outdoor Operations and Exploration: Forestry, geological exploration, and hiking teams maintain communication in areas without public network signals using this antenna.
Event and Activity Support: Used by event organizing committees and performance staff to ensure accurate transmission of dispatch instructions.
Emergency Rescue: Enables rapid deployment by fire and rescue teams at disaster sites, improving the communication range and reliability of UHF equipment.
Amateur Radio Communication: Used by amateur radio enthusiasts for UHF band communication, experimentation, and learning.
