Product Introduction
The GL-DY413 is a compact GSM rubber duck antenna with SMA male connector, specifically designed for 2G/3G networks operating at 890-960MHz and 1710-1990MHz frequencies. Featuring a durable rubber housing and 2.5dBi gain, this lightweight antenna provides reliable signal enhancement for mobile applications. Available in black or white, its robust construction ensures stable performance in various environmental conditions.
Application Scenarios
Mobile Field Equipment: Ideal for portable agricultural monitoring devices requiring reliable connectivity in remote areas
Legacy System Upgrades: Perfect for retrofitting older 2G/3G industrial equipment like vending machines or telemetry systems
Covert Installations: Suitable for discreet surveillance systems where low-profile antennas are essential
FAQ
Q: Why does the frequency range stop at 1990MHz instead of covering full 3G bands?
A: This antenna is optimized for specific regional 3G bands (e.g., EU's UMTS Band I), not all global 3G frequencies.
Q: Can the rubber housing be dyed a different color?
A: No, dyeing may introduce impurities that affect RF performance and material integrity.
Q: How does temperature affect the antenna's VSWR?
A: VSWR may fluctuate by ±0.2 in extreme temperatures (-40°C to +85°C) but remains within operational limits.
Q: Is the SMA connector compatible with quick-disconnect adapters?
A: Yes, but repeated quick-disconnect usage may wear down the brass threading over time.
Q: Why choose rubber over fiberglass for vibration-prone environments?
A: Rubber better absorbs mechanical vibrations without compromising signal stability.
Q: Can two antennas be mounted side-by-side without interference?
A: Maintain ≥20cm spacing to prevent mutual coupling between antennas.
