JEFA Tech Low Loss 240 FLEX is a perfect fit for RF components related to automation, remote sensing, and control. Connect your automation related RF devices such as cellular, satellite, GPS, and other sensors. It is durable and UV protected for devices that will be in outdoor harsh environments.
For Ham Radio and CB:
JEFA Tech Low Loss 240 FLEX / Premium RG-8X is a small, light and flexible low loss coax cable which is ideal for HAM Radio HF and VHF portable operation when high performance and small cable size and flexibility is important. It can also be used as a strain relief jumper inside your shack between your radio/amp and stiff feedline. Many HAMs use this cable for portable operations as it is easy to pack out, set up, and coil up again when operations have completed.
Beware of cheaper "RG-8X" coax sold by other sellers. Not all RG-8X is made the same. You invested in a quality transceiver and antenna, don't limit your system's potential with low quality feedline. JEFA Tech RG-8X, also known as Low Loss 240 FLEX, features a high density stranded copper center conductor, double shielding, and heavy-duty UV protected and direct burial capable jacket.
Attenuation per 100ft of JEFA Tech RG-8X cable for popular Ham Bands (lower is better):
40M - 0.8dB
20M - 1.1dB
6M - 2.07dB
2M - 3.62dB
70cm - 6.34dB
