Quick Reference
RFC600 Coaxial Cable
50 Ohm • DC – 6 GHz
RFC-600 is a budget-friendly 0.600" ultra-low-loss 50-ohm coaxial cable designed for very long feedline runs where performance is critical but LMR-600 pricing is a constraint. A practical choice for large outdoor antenna installations, long building penetrations, and cost-sensitive DAS projects requiring minimal signal loss.
RFC600 Attenuation
Signal loss in dB per 100 ft at standard RF frequencies.
| Frequency | Loss / 100 ft | Loss / ft | 6 ft | 25 ft | 50 ft | 100 ft |
|---|---|---|---|---|---|---|
| 100 MHz | 1 dB | 0.01 dB | 0.06 dB | 0.25 dB | 0.5 dB | 1 dB |
| 450 MHz | 2.2 dB | 0.022 dB | 0.13 dB | 0.55 dB | 1.1 dB | 2.2 dB |
| 900 MHz | 3.1 dB | 0.031 dB | 0.19 dB | 0.78 dB | 1.55 dB | 3.1 dB |
| 1.8 GHz | 4.5 dB | 0.045 dB | 0.27 dB | 1.13 dB | 2.25 dB | 4.5 dB |
| 2.4 GHz | 5.2 dB | 0.052 dB | 0.31 dB | 1.3 dB | 2.6 dB | 5.2 dB |
| 5.8 GHz | 8.6 dB | 0.086 dB | 0.52 dB | 2.15 dB | 4.3 dB | 8.6 dB |

Construction & Materials
Center Conductor
Bare copper clad aluminum, 4.13mm
The center conductor carries the RF signal. Material and diameter affect DC resistance, skin effect losses, and overall attenuation.
Dielectric
Foamed PE
The dielectric insulator separates the center conductor from the shield. PTFE dielectrics offer superior temperature stability and lower loss versus polyethylene.
Shield
Aluminum foil + tinned copper braid
The outer conductor provides the return path and shields the signal from external interference. More braid coverage means better EMI rejection.
Jacket
PE
The outer jacket protects the cable from physical damage, UV, chemicals, and moisture. PTFE and FEP jackets handle higher temperatures than PVC.
Velocity Factor
86% (c)
How fast the signal travels relative to the speed of light in vacuum. Higher velocity factor means shorter electrical wavelength per foot — important for phased array and delay-matched applications.
Max Voltage
600 VRMS
The maximum continuous operating voltage. Exceeding this can cause dielectric breakdown. Relevant for high-power transmitters and pulse applications.

Frequently Asked Questions
What is the impedance of RFC600?
RFC600 is a 50 Ohm coaxial cable. All standard RF systems (antennas, transceivers, test equipment) use 50-ohm impedance, so RFC600 connects directly without any matching network.
What frequency range does RFC600 support?
RFC600 is rated DC – 6 GHz. At higher frequencies, the attenuation per foot increases, so actual usable range depends on acceptable signal loss for your application.
How much signal loss does RFC600 have?
RFC600 has 1 dB of attenuation per 100 ft at 100 MHz, rising to 8.6 dB per 100 ft at 5.8 GHz. Use the attenuation table above to calculate loss for any specific length and frequency.
Are CoaxRF RFC600 cable assemblies made in the USA?
Yes. Every RFC600 assembly is hand-terminated and continuity tested at our US facility. We build each cable to order — nothing is pre-made or drop-shipped from overseas.
Can I order a custom length of RFC600?
Yes. In addition to our standard lengths (1, 6, 25, 50, 100 ft and longer), we accept custom-length orders through the Cable Builder. Custom assemblies ship within 1–2 business days.
