Quick Reference
LMR100 Times Coaxial Cable
50 Ohm • DC – 6 GHz
LMR-100A is a Times Microwave 50-ohm flexible coaxial cable with a 0.100" outer diameter, delivering significantly lower signal loss than RG-174 or RG-178 at the same form factor. Its foil-plus-braid shield offers 40 dB shielding effectiveness. A popular upgrade for short antenna pigtails and module connections in WiFi, cellular, and GPS applications.
LMR100 Times 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 | 5.1 dB | 0.051 dB | 0.31 dB | 1.28 dB | 2.55 dB | 5.1 dB |
| 450 MHz | 11.2 dB | 0.112 dB | 0.67 dB | 2.8 dB | 5.6 dB | 11.2 dB |
| 900 MHz | 16.2 dB | 0.162 dB | 0.97 dB | 4.05 dB | 8.1 dB | 16.2 dB |
| 1.8 GHz | 23.8 dB | 0.238 dB | 1.43 dB | 5.95 dB | 11.9 dB | 23.8 dB |

Construction & Materials
Center Conductor
Bare copper clad steel, 0.93mm
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
80% (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 LMR100 Times?
LMR100 Times is a 50 Ohm coaxial cable. All standard RF systems (antennas, transceivers, test equipment) use 50-ohm impedance, so LMR100 Times connects directly without any matching network.
What frequency range does LMR100 Times support?
LMR100 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 LMR100 Times have?
LMR100 Times has 5.1 dB of attenuation per 100 ft at 100 MHz, rising to 46 dB per 100 ft at 5.8 GHz. Use the attenuation table above to calculate loss for any specific length and frequency.
Are CoaxRF LMR100 Times cable assemblies made in the USA?
Yes. Every LMR100 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 LMR100 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.
