How to choose the RG316 Coax and LMR100 Coax? Which one is better?

LMR100 and RG316 are both coaxial cables utilized for different purposes, including telecommunications and communications applications. They both have an impedance of 50 Ω low loss and attenuation characteristics communication wires and have very similar purposes; this makes it very difficult to differentiate them. This article will clarify the small differences between them to help you adequately differentiate an RG316 cable from an LMR 100 cable, and make it much easier to decide which is a better option for your projects. It may vary in effectiveness based on the circumstances of the environment they are to be utilized in, even if they are both coax cable. When you have a total understanding of both cables, you will know what kind of cable to use, considering the external conditions so that you may select the proper type of cable.

RG316 Coaxial Cable

RG316 is a coax communication wire with a military rate. This cable can be utilized in a wide range of applications such as in military equipment, the transmission of radio frequency signals, direct burial, and telecommunications applications. It is an excellent option for applications that need high performance and stability in high-temperature conditions or need to have minimal installation space. Coax RG316 can be even employed for high-frequency interconnections between PCB in telecommunications devices. RG316 coax is also a low loss cable. Because of the large size’s conductor, the attenuation of RG316 is lower than other alternatives in this category, which is in accordance with MIL-DTL-17 specifications.

LMR 100

LMR 100 is a flexible communication cable. This cable is an excellent option in short antenna feeder runs and jumper assemblies applications that are mainly in wireless communication systems. LMR 100 can be utilized in WLL, GPS, WLAN, and applications that need easily routed, low-loss cables. This cable has a flexible external conductor and can allow the tightest bend radius of any wire that is similar size and performance. It is also the lowest loss of any flexible cable. LMR cable can be used as a drop-in replacement for RG 316 or RG 174 cable. The double-shielded external conductor provides exceptional RF shielding exceeding 90 dB, and 2.79 mm overall diameter makes the cable kind appropriate for high-frequency microwave applications up to 63 GHz, even though they are rarely seen above 6 GHz.

When seeing the list of specifications (low loss or attenuation, construction ) of Coax cable RG316 and LMR-100, we can find that both cables are built differently. 


  • LMR-100 has a solid bare copper clad steel conductor, where RG316 has a stranded silver-covered copper clad steel conductor.
  • RG-316’s stranded conductor makes it more flexible than the solid conductor of LMR-100. 
  • The principal difference is that RG316 has a higher temperature rating that is caused due to the Fluorinated Ethylene Copper (FEP) materials Jacket type of RG-316 coax. This enables the cable to be utilized in specific applications that need a higher temperature environment in comparison to the LMR-100.
