Product Introduction
Professional Narrow-Band High-Precision Tuning
Precisely optimized for the 474-478MHz frequency band, achieving excellent VSWR (VSWR <1.5) within this narrow band. This ensures maximum signal transmission efficiency, eliminates frequency waste, and provides clean, stable communication quality for professional applications.
Superior High Gain, Long-Distance Communication Powerhouse
With a gain of up to 6.5dBi, it significantly improves signal coverage and receiver sensitivity. Compared to ordinary 3dBi antennas, the effective communication distance is greatly increased, making it ideal for open areas or scenarios requiring long-distance communication.
High-Quality Components and Robust Construction
Utilizing an FEM interface and low-loss RG174 cable, it ensures connection stability and signal integrity. The antenna's total length is 942mm, and its precise structural design provides excellent mechanical strength, sufficient to withstand the vibrations and wind resistance of moving vehicles.
High Power Handling, Stable and Reliable
Supports up to 50W of input power, meeting the high-power output requirements of professional-grade mobile radios. It ensures powerful signal transmission and uninterrupted communication even in critical moments.
Highly Targeted, Outstanding Performance in Dedicated Scenarios
Although it operates on a specific frequency band, this very focus allows it to outperform broadband antennas at certain frequencies (such as 476MHz), providing an excellent antenna solution for professional wireless audio transmission, remote control, and other equipment.
Application Scenarios
Professional Wireless Audio Systems: Wireless microphone receiving antennas for broadcast television recording vehicles and mobile studios.
Industrial Telemetry and Remote Control: Remote control of special engineering vehicles and UAV ground station control links.
Fixed Frequency Repeaters: Outdoor antennas used as fixed repeaters in specific locations (such as mines and farms).
Dedicated Service Frequency Band Communication: Suitable for vehicle communication in specific industries or government departments allocated the 474-478MHz frequency band.
Amateur Radio: Serving licensed amateur radio enthusiasts for vehicle-mounted communication within this frequency band.
FAQ
Q: Can this antenna only be used in the 474-478MHz range?
A: Yes. It is specifically optimized for this narrow frequency band; performance will significantly decrease outside this range. Please ensure your device operates within this frequency range.
Q: Why is this antenna so long (942mm)?
A: The physical length of an antenna is related to its operating wavelength and gain. A longer element is needed for optimized design to achieve a high gain of 6.5dBi, reflecting its high performance.
Q: What is an FEM connector? How do I connect it to my device?
A: An FEM is a threaded connector. If your device uses a common SL-16-J (male) or SMA (male) connector, you will need an "FEM to SL-16-J" or "FEM to SMA" adapter.
Q: What are the advantages of a 6.5dBi gain in practical use?
A: High gain means that energy is radiated more concentratedly in the horizontal direction, effectively extending the communication distance and achieving better reception in weak signal areas.
Q: The antenna is quite heavy (600g), is it securely mounted?
A: We recommend using a sturdy magnetic base or clamp mount for mounting. As long as the base is of reliable quality, it can be securely fixed and will function without problems during normal operation.
Q: Can it be used in homes or as a base station?
A: Yes. As long as the frequency is matched and it is used with a suitable mounting base (such as a bracket), it can be used as a high-performance base station antenna.
