Product Description

390-440MHz 8dBi Omnidirectional Fiberglass Antenna, Model GL420V-8

The GL420V-8 is a high-performance omnidirectional fiberglass antenna designed for the 390-440 MHz UHF frequency range, making it ideal for professional land mobile radio (LMR), public safety, and specialized mobile communication systems. Engineered for long-range outdoor deployment, it provides complete 360° horizontal coverage with a focused 30° vertical beamwidth, delivering an 8 dBi gain for extended reach and reliable connectivity. The antenna features a durable white fiberglass radome, built-in DC-ground lightning protection, and a bottom-mounted N-female connector for secure and weather-resistant installation. With a tall, slender design (Φ32×2230 mm) and a weight of 2.5 kg, the GL420V-8 is built to operate reliably in harsh environments, supporting temperatures from -40°C to +60°C and wind speeds up to 60 m/s. Its high power handling (100 W) and low VSWR (≤2.0) ensure efficient signal transmission, making it a robust choice for base stations, repeater sites, and mission-critical communication networks.

FAQ

Q: What radio systems typically operate in the 390-440 MHz band?
A: This band is commonly used for professional land mobile radio (LMR), public safety communications (including TETRA and DMR systems), military tactical radios, and some industrial telemetry applications.

Q: How is the antenna mounted given its height?
A: The antenna is designed for mast mounting using poles with diameters between 35 mm and 60 mm. Heavy-duty U-bolts or adjustable clamps are recommended to ensure stability, especially in high-wind areas.

Q: Does the antenna require a ground plane or radials?
A: No, this is a complete omnidirectional antenna that does not require an external ground plane or radials for proper operation.

Q: What type of coaxial cable is recommended for this antenna?

A: Use low-loss, outdoor-rated coaxial cable (such as LMR-400 or equivalent) with an N-male connector. Ensure all connections are properly weather-sealed to prevent moisture ingress.

Q: Is this antenna suitable for high-wind coastal or mountainous regions?
A: Yes, with a rated wind velocity of 60 m/s (~216 km/h) and a streamlined fiberglass design, it can withstand severe weather conditions when properly mounted on a sturdy structure.
