Frequently Asked Questions
Q: What is the difference between RG402 and RG141 coaxial cable?
A: Both RG402 and RG141 are semi-rigid/semi-flexible coaxial cable standards commonly used in RF and microwave applications. RG402 typically features a 0.141-inch outer diameter and is widely used in test and measurement setups, while RG141 is a similar specification with a PTFE dielectric for enhanced high-frequency performance. This cable is compatible with both standards, giving you broad versatility across RF systems.
Q: Can this RF cable be cut to a custom length?
A: Yes! Custom lengths are available. Simply contact us with your required specification before placing your order and we will be happy to accommodate your needs.
Q: What types of connectors are compatible with this coaxial feeder cable?
A: This semi-flexible coaxial cable is compatible with standard RF connectors designed for RG402/RG141 specifications, including SMA, N-type, BNC, and similar RF connector families. Always verify the connector impedance (typically 50 Ω) matches your system requirements.
Q: Is this cable suitable for outdoor or weatherproof installations?
A: This cable is primarily designed for bench, laboratory, and indoor RF assembly use. For outdoor installations, additional weatherproofing measures or an outdoor-rated cable variant is recommended to ensure long-term performance.
