Frequently Asked Questions (FAQ)
Q1: Can this SMA male extension RF adapter cable directly replace standard RG58 cables?
A: Absolutely, and it delivers better performance. Compared to RG58,RG316AdapterThe outer diameter is slimmer (2.55mm vs. 5mm), offering greater flexibility and heat resistance up to
150°C (RG58 typically only 80°C), ideal for signal connections inside precision instruments or in high-temperature environments.
Q2: Can this adapter cable be customized for length? What is the minimum order quantity (MOQ)?
A: Yes, we support it.SMA RF Adapter Cablefully customizable. You can specify any length (e.g., 10cm, 50cm, 1m, etc.) and different fitting combinations (e.g.,
SMA conversionSMA adapter cableSMA-to-BNC adapters, etc. As a direct factory supplier, we offer flexible MOQ policies and accept sample orders, with even better pricing for bulk quantities.
Excellent.
Q3: What is the approximate signal attenuation of this cable on the 5.8GHz frequency band?
A: Based on the RG316 attenuation curve, at 5.8GHz (commonly used for drone video transmission or Wi-Fi), attenuation per meter is approximately 2.2dB to 2.4dB. For short-range
Extending the cable by up to 1 meters results in negligible signal loss, fully meeting high-fidelity transmission requirements.
Q4: What is the difference between silver-plated conductors and pure copper conductors? Why use silver-plated copper-clad steel?
A: In high-frequency signal transmission, the skin effect causes current to flow primarily on the conductor's surface.Silver PlatedProvides excellent surface conductivity and reduces high-frequency resistance; whileCopper-clad steel
The core conductor provides higher tensile strength, preventing breakage during frequent plugging/unplugging or bending, thereby extending the cable's lifespan.RF adapter cablelifespan.
