3.5 mm TRRS vs. Coaxial Cable Types (RG Series)

Comparing 2 standards across 14 specifications. 14 key differences identified.

Comparing:
3.5 mm TRRS
Coaxial Cable Types (RG Series)
3.5 mm TRRS →

3.5mm TRRS connectors transmit stereo audio plus a microphone signal over four conductors. CTIA wiring places ground on Ring 2 and mic on the sleeve; OMTP swaps ground to the sleeve and mic to Ring 2, causing muted or distorted audio when the two are mixed.

Coaxial Cable Types (RG Series) →

Coaxial cables transmit high-frequency radio frequency (RF) and television signals under MIL-C-17 standards through a concentric center conductor, dielectric insulator, metallic shield, and outer jacket, categorized into 75-Ohm video/broadband series (RG-6, RG-59, RG-11) and 50-Ohm wireless/RF series (RG-58, RG-8X, LMR-400).

Governing Standards
— MIL-C-17 / SCTE (Society of Cable Telecom Engineers) / ANSI/TIA-568
RG-6 / RG-6 Quad Shield (75Ω)
— Center Conductor: 18 AWG (1.02 mm) | Outer Dia: 6.86 mm (0.270") | Satellite TV, Cable DOCSIS 3.1, HDTV Antennas
RG-59 (75Ω Legacy / CCTV)
— Center Conductor: 20–22 AWG (0.81 mm) | Outer Dia: 6.15 mm (0.242") | Baseband analog CCTV, short-run composite video
RG-11 (75Ω Long-Distance Drop)
— Center Conductor: 14 AWG (1.63 mm) | Outer Dia: 10.3 mm (0.405") | Heavy low-loss underground long-run drops
RG-58 (50Ω RF / Two-Way Radio)
— Center Conductor: 20 AWG (0.90 mm) stranded | Outer Dia: 4.95 mm | CB Radio, amateur VHF/UHF, Wi-Fi pigtails
LMR-400 (50Ω Ultra Low-Loss)
— Center Conductor: 10 AWG (2.74 mm) solid copper-clad aluminum | Cellular towers, 2.4/5GHz Wi-Fi antenna masts
Impedance Matching Rule
— Never mix 50Ω and 75Ω systems; impedance mismatch causes high Standing Wave Ratio (SWR) and RF reflections
