FAQ

Q: What's the difference between active and passive products?
A: Dynamic models incorporate a built-in speaker for upgraded affectability, whereas detached models offer a more direct, interference-free operation.

Q: Can your product be used for 5G testing?
A: Yes, our high-frequency models are suitable for 5G applications up to 3 GHz.

Q: How do I maintain the antenna for optimal performance?
A: Store in a dry environment, maintain a strategic distance from physical impacts, and intermittently check associations for erosion or looseness.

Q: Are calibration services available?
A: Yes, we offer calibration services to ensure your antenna maintains its precision over time.

Q: Can the antenna be used outdoors?
A: Our recieving wires are planned for both indoor and open air utilize, with weather-resistant coatings for durability.
