Product Description

470-510MHz 2.5dBi Omnidirectional Fiberglass Antenna, Model GL500V-2

The GL500V-2 is a compact and versatile omnidirectional fiberglass antenna engineered for the 470-510 MHz UHF frequency range, ideal for applications such as wireless microphone systems, in-ear monitoring, short-range data links, and specialized professional communications. Designed for flexible deployment in both fixed and mobile scenarios, it provides full 360° horizontal coverage with a 30° vertical beamwidth, offering a modest 2.5 dBi gain suitable for close to medium-range connectivity. The antenna features a lightweight gray fiberglass radome, integrated DC-ground lightning protection, and a bottom-mounted N-male connector for straightforward installation. With a slender profile (Φ20×295 mm) and minimal weight (0.25 kg), the GL500V-2 can be easily mounted using a magnetic base or other mounting accessories. It operates reliably across a temperature range of -40°C to +60°C and withstands wind speeds up to 60 m/s, making it a durable and practical choice for portable, temporary, or permanent outdoor installations where size and ease of use are priorities.

FAQ

Q: What is the typical use of the 470-510 MHz frequency range?
A: This band is commonly allocated for wireless audio equipment (microphones, in-ear monitors), some land mobile radio services, amateur radio, and short-range telemetry/data applications in various regions.

Q: Can I use a magnetic mount with this antenna?
A: Yes, the antenna is compatible with magnetic mounting bases and other accessory mounts, making it easy to install temporarily on vehicles, metal surfaces, or poles.

Q: What is the maximum cable length recommended for this antenna?
A: While the antenna itself does not limit cable length, for optimal performance at UHF frequencies, use high-quality low-loss coaxial cable and keep runs as short as practical, typically under 10-15 meters unless using very low-loss cable.

Q: Does this antenna require tuning or adjustment after installation?
A: No, the antenna is pre-tuned at the factory for the 470-510 MHz band and does not require user adjustment. Simply ensure secure mounting and proper connector mating.

Q: Is the antenna suitable for permanent outdoor installation?
A: Yes, with its fiberglass radome, wide temperature rating, and integrated lightning protection, it can be used for permanent outdoor installations. Ensure all connections are properly weather-sealed for long-term reliability.
