FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why choose RG-223/U over standard RG-58C/U?

Standard RG-58C/U has a single tinned-copper braid (~50 dB shielding) and is limited to ~1 GHz, whereas RG-223/U features a silver-plated solid copper center conductor and dual silver-plated copper braids (> 90 dB shielding), extending usable frequency to 12.4 GHz and eliminating crosstalk in dense equipment racks.

How does RG-223/U compare to RG-400/U?

Both cables are 50 Ω double-SPC-braided coaxial cables with a 2.95 mm dielectric diameter; RG-223/U uses a solid SPC center conductor and PE/PVC insulation (-40 to +80 °C) for cost-effective telecom and lab jumpers, whereas RG-400/U uses a 19-strand SPC conductor and PTFE/FEP (-55 to +200 °C) for aerospace and high-temperature service.

Do standard RG-58 BNC connectors fit RG-223/U?

While both share a 2.95 mm dielectric diameter, RG-223/U's second braid increases its outer diameter to 5.38 mm (vs 4.95 mm for RG-58), so you should select crimp ferrules sized for the RG-223/RG-55 group (0.212 in OD). Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

Is RG-223/U suitable for 10 MHz GPS/rubidium clock distribution?

Yes, its > 90 dB double-braided silver-plated copper shield prevents external switching noise from corrupting low-phase-noise 10 MHz and 1 PPS reference signals. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
