Overview of LMR400
Times Microwave's LMR-400 is designed for adaptability, low loss, RF shielding, and wearability. The LMR-400 has the narrowest bend radius of any cable of comparable size and performance due to its cable architecture. The cable has the lowest loss of any comparable cable. This cable offers 90 dB of RF shielding and is ideal for EMI-prone environments. The LMR-400 is suitable for both indoor and outdoor use. Use Times Microwave's LMR-400 cable for any application that necessitates a low-loss, conveniently routed RF cable (e.g. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas). The LMR-400 cable can be used in place of an RG-8 cable.
Overview of LMR-240
Pasternack's LMR-240 part number refers to a flexible LMR-240 coax cable. The 50 Ohm Pasternack LMR-240 flexible coax cable has a PE (F) dielectric. Our LMR-240 coax has a PE jacket with a thickness of 0.24. This Pasternack cable features a shield count of two, RF shielding of 90 dB, and a maximum frequency of 5.8 GHz. At 1 GHz, the attenuation of the LMR-240 coax cable is 8 dB.
Over 40,000 RF, microwave, and millimeter-wave components are made up of Pasternack LMR-240 coax cables. LMR-240 cables and other RF components are available for same-day shipping anywhere in the world. Custom RF cable assemblies made from LMR-240 or other types of coax can also be constructed and dispatched on the same day.
Conclusion of LMR240 VS LMR400
LMRÂź240 is also a 50 Ohm impedance outdoor rated flexible low loss communications cable. It's developed for short feeder runs in applications like GPS, WLAN, and mobile antennas. The flexible communications coax LMRÂź400 has a 50 Ohm impedance.
LMR400 cable has a lower loss than LMR240 cable, but it is thicker and less flexible, making it more difficult to work with. It is available in lengths ranging from 2' to 100' and is intended for use with antennas and amplifiers that do not include wiring. Although LMR240 is half the size and has twice the attenuation loss of LMR400, the difference does not appear to be significant, and both appear to be the highest quality and lowest loss alternatives for marine coax. The DB (waterproof) version is also available. I'm leaning toward the LMR240 because of its smaller diameter, and I'd use a messenger line to run the wire up.
