FAQ

Questions engineers ask first

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

Why did MIL-DTL-17 replace RG-8/U with RG-213/U?
Early RG-8/U cables used standard PVC jackets whose plasticizers migrated into the polyethylene dielectric over time, increasing RF loss; RG-213/U mandates a non-contaminating Type IIA PVC jacket and tighter dimensional tolerances under MIL-DTL-17/74. 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.
When should RG-214 be specified instead of RG-213?
Specify RG-214 when operating above 1 GHz (up to 11 GHz), in high-EMI transmitter rooms, or in corrosive marine environments—RG-214 upgrades both the 13 AWG center conductor and dual outer braids to silver-plated copper. 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.
How much RF transmitter power can RG-213 handle?
Thanks to its 7.24 mm solid PE dielectric (3,700 V rms rating) and 3.09 mm² copper conductor, RG-213 handles up to 4.8 kW continuous CW at 10 MHz, 1.4 kW at 100 MHz (VHF), and 620 W at 400 MHz (UHF). 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.
Which standard connectors fit RG-213?
All standard 0.405-inch (10.3 mm) coaxial connectors fit RG-213, including Type N (UG-21), UHF PL-259, 7/16 DIN, BNC, and TNC clamp or crimp plugs. 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.
