●Special terrain signal enhancement: Professional solutions for areas with severe signal attenuation, such as hilly areas and forests
FAQ
Q: What is the suitable signal reception distance for the GLH311?
A: Optimized for medium-to-long-distance signal reception (40-70 km), performing excellently in extremely weak signal environments.
Q: How should I choose between the F and IEC interfaces?
A: The F interface is suitable for standard coaxial cable connections, while the IEC interface is suitable for professional equipment connections. Choose according to the actual equipment interface.
Q: What power supply issues should be considered during installation?
A: A stable AC 220V power supply must be used. It is recommended to use a voltage regulator in areas with unstable voltage.
Q: What is the product's waterproof rating?
A: IP65 protection rating, completely dustproof and water-resistant, suitable for long-term outdoor installation.
Q: Can the amplifier gain be adjusted?
A: It adopts a fixed gain optimization design; the system will automatically and intelligently adjust according to signal strength.
Q: What are the recommendations for installation height?
A: We recommend an installation height of 8-15 meters, avoiding obstructions, and facing the signal tower.
