RG cables structural design and signal integrity

The RG coaxial cable series minimizes insertion loss across long transmission lines. Solid center conductors provide phase stability for test instruments. Stranded configurations ensure mechanical flexibility for dynamic routing requirements.

Core dielectrics include PE, foam PE (F), and solid PTFE. These materials establish signal propagation velocities between 65.9% and 85%. This architecture controls signal delay and reduces internal power dissipation.

Coaxial RG cables utilize outer shields ranging from single copper to triple-shielded matrices. Multiple conductive layers prevent electromagnetic interference in dense server racks. This maintains signal isolation across sensitive aerospace and military enclosures. These shielding structures ensure strict MIL-STD compliance for defense systems.

Outer jackets feature standard PVC, PVC (NC), and FEP. Non-contaminating PVC (NC) jackets prevent plasticizer migration into the dielectric core. This chemical stability extends the physical lifespan of the cable.

PTFE cores and extruded FEP jackets support high-temperature environments. These RG cables operate continuously up to 200 °C. Jacket diameters range from 2.54 mm to 10.29 mm.

RG Coaxial Cable FAQs

How does exceeding the minimum bend radius alter electrical performance in RG402 and RG405 cables?
Exceeding bend limits (6.35 mm for RG402, 1.27 mm for RG405) deforms the PTFE core. This alters concentricity between the inner conductor and outer shield. The characteristic impedance shifts away from 50 Ω. This creates localized reflections, sharp VSWR spikes, and permanent insertion loss up to 40 GHz.
What architectural differences change the velocity of propagation between standard RG58 and RG6-CATV?
Standard RG58 uses a solid PE core. It yields 65.9 % propagation velocity and 65.62 dB/100 m attenuation at 1 GHz. Conversely, RG6-CATV integrates a foam PE (F) dielectric. This cellular structure increases velocity to 85 % and minimizes dissipation losses. With triple-shielding, attenuation drops to 21.49 dB/100 m at 1 GHz.
Which RG coaxial cable series configurations perform reliably in high-temperature environments?
Standard PE dielectrics soften and fail above 80 °C. High-temperature environments require variants like RG142, RG179, RG316, RG393, and RG400. These configurations feature solid PTFE core dielectrics and extruded FEP outer jackets. This material combination maintains mechanical and phase stability up to 200 °C.
When is it necessary to specify double-shielded configurations instead of single-shielded variants?
Single-shielded RG coax cables typically provide 40 dB to 60 dB of RF isolation. High-interference environments demand greater electromagnetic interference protection. Double-shielded configurations utilize two overlapping outer conductive layers. This dual-layer structure increases overall shielding effectiveness to approximately 90 dB. Consequently, this prevents signal leakage within densely packed equipment racks.
How does center conductor construction dictate the mechanical flexibility of RG series cables?
Solid center conductors deliver lower insertion loss and higher phase stability. However, they are susceptible to metal fatigue during repeated bending. Conversely, stranded inner conductors utilize multiple fine wires twisted together. Configurations like the 19-strand RG400 or 7-strand RG316 withstand continuous dynamic flexing. This stranded design ensures mechanical reliability in high-vibration environments.
What are the electrical consequences of terminating 75 Ω cables with standard 50 Ω connectors?
Terminating 75 Ω rg coaxial cables such as RG59 or RG6-CATV with standard 50 Ω interfaces creates an impedance mismatch. This physical discontinuity reflects a portion of the RF signal back toward the source, increasing the VSWR at the connection point. For precision systems, this resulting reflection degrades overall power transmission efficiency.
