Frequently Asked Questions (FAQ):
Does this cable support SMA female or BNC connectors?
Current model is standard N male to SMA male. For other connector combinations (e.g., SMA female...Connector, BNC connectors, etc.). Contact customer service for custom options. Supports multiple connection types.
Adapter combination.
What is the difference between cable outer diameters 4.16mm and 6.88mm?
4.16mm is suitable for compact spaces with lower power requirements (10-50W).Module; 6.88mm is suitable for high-power applications (50-100 W) or those requiring greater mechanical strength.
Select the configuration based on your actual power requirements and available installation space.
Is it suitable for outdoor use or high-temperature environments?
The blue sheath offers moderate weather resistance, but a protective conduit is recommended for long-term outdoor use. Operating temperature range: -40°C to +85°C, suitable for most industrial and communication applications.
Device Requirements.
How to check if a cable is damaged or aging?
Insertion loss and return loss can be measured using a network analyzer. Significant deviations from nominal values (e.g., loss increase >1 dB or VSWR >1.5) indicate that the cable is defective.
May be damaged or aged; replacement is recommended.
