Frequently Asked Questions
Q: What devices is this BNC/SMA to USB female RG174 cable compatible with?
A: This cable is compatible with any device that uses a standard BNC or SMA connector, such as SDR dongles, RF analyzers, GPS receivers, amateur radio equipment, and CCTV cameras. The USB female end connects to USB-powered devices or computer interfaces that accept a USB plug.
Q: What does "low loss" mean for an RG174 coaxial cable?
A: "Low loss" refers to the cable's ability to transmit RF signals with minimal attenuation (signal degradation) along its length. The RG174 coax is engineered with a solid center conductor and quality shielding to keep signal levels stable, especially important for RF, SDR, and antenna applications operating at higher frequencies.
Q: What is the impedance of this cable and why does it matter?
A: This cable has a 50-ohm impedance, which is the standard for most RF and antenna systems, including SDR receivers, ham radio gear, and test equipment. Matching impedance between your cable and connected devices minimizes signal reflection and maximizes transmission efficiency.
Q: Is any assembly required to use this cable?
A: No assembly is required. The cable arrives fully pre-terminated with connectors on both ends, ready for immediate use. Simply select your desired length and connector variant from the options above.
