Description

Note: The LMR240 low loss cable has connectors that directly connect on the back of the Helium Hotspot (RP-SMA) and another end to your outdoor antenna (N-Type). It comes with RP-SMA Male and N Female connectors.

LMR240 cable is an ultra Flexible Low Loss Communications Coaxial cable, supplied in four variations of length, 10 meters, 6 meters, 4 meters, and 2 meters. Before you proceed to get any type of cable for your communication setup, make sure you know to choose the right connectors for the cable. This video will explain everything you need to know about the connectors and Reverse Polarity:

Note: The hotspot and antenna are NOT INCLUDED. Please get them separately.

 

Why choose LMR240?

LMR240 has excellent reliability, unsurpassed flexibility, and ultra-low attenuation. The LMR240 cable has loss figures comparable to the extremely rigid corrugated coaxial cables however manages to achieve similar flexibility to that of high loss Radio Guide (RG) Cables. LMR240 is around 40% lower attenuation than competing RG Air-Dielectric type Cables.

All standard LMR coaxial cable comes with a UV-resistant, PE Jacket. This helps to ensure the cable jacket can withstand harsh outdoor environments and UV rays from sunlight, this is designed to last for up to 20 years of outdoor service.

 

How are the LMR240 low loss figures achieved?

This is achieved due to the cable construction specifications. The center conductor uses a high conductivity, bare copper clad covered aluminum center conductor material. The dielectric is nitrogen injected, foamed, closed-cell, Polyethylene which helps achieve 83% Velocity of Propagation. The Dielectric has an Aluminum foil outer conductor, which is chemically bonded onto it. Due to the cable construction, the attenuation is significantly lower as compared to single shielded coaxial cables.

Note: Please SHUTDOWN the hotspot first when changing to the new coaxial cable.

You can refer to this video for the full setup of the Helium hotspot with the LMR400 coaxial cable. LMR400 is just another version of  LMR240, so the setup should be compatible with the LMR240 cable too.

Note: Please note that the person in the video was using a different type of connector for both antenna and coaxial cable.
