Product Description

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

The GL420V-8 is a high-performance, vertically polarized omnidirectional fiberglass antenna designed for the 390-440 MHz UHF frequency band. Engineered for reliable long-range communication in demanding outdoor environments, it offers a substantial 8 dBi gain and a focused 30° vertical beamwidth paired with full 360° horizontal coverage. This tall, slender antenna (32×2230 mm) is constructed with a durable white fiberglass radome, providing excellent weather resistance and structural integrity. It features an N-female connector at the bottom, supports up to 100W input power, and includes integrated DC-ground lightning protection for enhanced safety. Built to withstand harsh conditions, the GL420V-8 operates reliably from -40°C to +60°C and can endure wind speeds up to 60 m/s. Its design is ideal for fixed base stations, marine communications, public safety networks, and industrial telemetry systems requiring robust, high-gain UHF coverage.

FAQ

Q: What is the typical range of this antenna?
A: Range depends on terrain, transmit power, and receiver sensitivity. With 8 dBi gain and 100W capability, typical line-of-sight range can exceed 50 km under optimal conditions.

Q: How should this tall antenna be mounted for stability?
A: Use sturdy mounting hardware for poles with diameters of 35-60 mm. Consider using guy wires for additional stability, especially in areas with high winds or seismic activity.

Q: Does the antenna require grounding?
A: Yes, the DC-ground lightning protection feature requires proper grounding. Connect the mounting hardware and cable shield to a certified earth ground system following local electrical codes.

Q: Can this antenna be used in saltwater environments?
A: The fiberglass radome provides good corrosion resistance, but all metal components (mounting hardware, connectors) should be marine-grade or regularly maintained in coastal installations.

Q: What type of coaxial cable is recommended?
A: Use low-loss, high-quality coaxial cable (such as LMR-400 or equivalent) with an N-male connector. For long cable runs, consider larger diameter cables to minimize signal loss at UHF frequencies.
