What is LMR400?
LMR400 is a type of coaxial cable that is widely used in various applications, particularly in the field of telecommunications and radio frequency (RF) technology. It is known for its low loss and excellent shielding capabilities, making it ideal for transmitting high-frequency signals with minimal signal degradation.
What is LMR400 used for?
LMR400 is primarily used for long-distance communications and RF applications where low loss and high performance are critical. It is commonly used in wireless networks, radio transceivers, antennas, cellular base stations, satellite communication systems, and other similar applications that require efficient signal transmission.
Features
- Low Loss: LMR400 has a low attenuation or loss characteristic, which means it can transmit signals over longer distances with minimal signal degradation. This feature makes it suitable for applications that require extended cable runs or where signal quality is crucial.
- Excellent Shielding: LMR400 has a dual shield construction, comprising an aluminum foil layer and a tinned copper braid, which provides exceptional electromagnetic interference (EMI) and radio frequency interference (RFI) shielding. This shielding capability helps minimize signal loss and external interference, ensuring reliable signal transmission.
- High Power Handling: LMR400 has a relatively high power handling capacity, allowing it to handle higher power levels without significant signal loss or damage to the cable. This feature makes it suitable for applications that involve high-power RF transmissions, such as in broadcasting or military communications.
- Wide Frequency Range: LMR400 is designed to operate within a wide frequency range, typically from DC (Direct Current) up to 6 GHz. This broad frequency range makes it versatile and compatible with various RF systems and equipment.

Compare With Others
LMR400 vs RG8
RG8 is a commonly used coaxial cable that offers good performance at a lower cost. However, when compared to LMR400, there are some key differences. LMR400 has lower loss and better shielding, making it more suitable for longer cable runs and higher frequencies. Additionally, LMR400 has a larger diameter, which contributes to its lower loss characteristics.
LMR400 vs RG58
RG58 is a thinner and less expensive coaxial cable commonly used in shorter cable runs. While RG58 may be suitable for certain applications, LMR400 outperforms it in terms of lower loss, better shielding, and higher power handling capabilities. If you require longer cable runs or need to transmit signals over higher frequencies, LMR400 is the superior choice.
LMR400 vs RG213
RG213 is another popular coaxial cable known for its robustness and durability. However, when comparing LMR400 with RG213, LMR400 once again comes out on top in terms of lower loss and better shielding. LMR400 is designed to handle higher power levels and is more suitable for applications requiring long cable runs or higher frequency transmissions.
LMR400 vs KMR400
KMR400 is a variant of LMR400 that is specifically designed for outdoor use and offers enhanced weather resistance. While both cables share similar characteristics in terms of low loss and high performance, KMR400 has additional features such as UV protection and moisture resistance. If you need a coaxial cable for outdoor installations, KMR400 provides added durability and longevity.
FAQs
