Quick Reference
LMR600 ULTRA FLEX Times Coaxial Cable
50 Ohm • DC – 6 GHz
LMR-600-UltraFlex provides the ultra-low-loss performance of LMR-600 in a more flexible form factor, enabling easier routing around obstacles and through conduit without specialized bending tools. Specified for cell tower jumpers, rooftop DAS assemblies, and high-demand installations where the stiffness of standard LMR-600 would complicate routing.

Construction & Materials
Center Conductor
Stranded bare copper, 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
PVC
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
2500 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 LMR600 ULTRA FLEX Times?
LMR600 ULTRA FLEX Times is a 50 Ohm coaxial cable. All standard RF systems (antennas, transceivers, test equipment) use 50-ohm impedance, so LMR600 ULTRA FLEX Times connects directly without any matching network.
What frequency range does LMR600 ULTRA FLEX Times support?
LMR600 ULTRA FLEX Times 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 LMR600 ULTRA FLEX Times have?
LMR600 ULTRA FLEX Times has 1.1 dB of attenuation per 100 ft at 100 MHz, rising to 8.8 dB per 100 ft at 5.8 GHz. Use the attenuation table above to calculate loss for any specific length and frequency.
Are CoaxRF LMR600 ULTRA FLEX Times cable assemblies made in the USA?
Yes. Every LMR600 ULTRA FLEX Times 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 LMR600 ULTRA FLEX Times?
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.
