LMR240 VS. LMR400: What’s The Difference Between Them?

The Times Microwave LMR400 is designed for flexibility and low loss, as well as protection from RF radiation and wearability. It has the most narrow stretch radius of any comparable cable in size and performance because of its cable's design. It has the lowest loss of any similar cable. The cable has 90 dB of RF shielding and is suitable for environments that are prone to EMI. The LMR400 cable is ideal for indoor and outdoor usage. Make use of Times Microwave's LMR400 cable to fulfill any need for an efficient, low-loss wireless RF connection (e.g. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas). It could be used instead for an RG-8 cord.

The Pasternack's LMR240 part number is a coax cable that is flexible. This 50 Ohm Pasternack LMR-240 coax cable is made of PEE (F) dielectric. The LMR240 cable has PE jackets with an average thickness of 0.24. The Pasternack cable has shielding two with RF shielding that is 90 dB and a maximum frequency of 5.8 GHz. The attenuation for the LMR240 coax cable is 8 dB.

More than 40000 RF, microwave, and millimeter-wave components comprise Pasternack LMR240 cables. It as well as other components of RF are available for shipping same day all over the world. Custom-designed RF cable assemblies constructed and other types of coax may also be made and shipped the same day.

LMR240 is also an outdoor 50 Ohm impedance high-quality, low-loss flexible communications cable. It's designed for short feeder runs that are used in applications such as GPS wireless, WLAN, or mobile antennas. The flexible coax for communication LMR400 is 50 Ohm in impedance.

LMR400 cable has lower losses as compared to LMR240 cable, however, it is heavier and more brittle, making it harder to deal with. It comes in lengths of 2 100' up to 2'. It is designed for use with amplifiers and antennas which do not have wiring. While LMR240 is only smaller and has twice the attenuation loss as LMR400, the differences do not seem to be significant. Moreover, both are believed to be the best quality and lowest loss options in marine coax. It is possible to purchase the DB (waterproof) variant is available too.
