JEFA Tech Low Loss Series Coax Cable Assemblies

Low Loss 195 Cable Assemblies
JEFA Tech Low Loss 195 is thin and light and is great for permanently installed short pigtails. The greatest numbers of connector options are available with Low Loss 195. It has a 0.195 inch outside diameter and features a solid center conductor for greatest performance, foam dielectric and double shielding for low signal loss and interference rejection, combined with UV resistant Polyethylene jacket.

Low Loss 240 FLEX Cable Assemblies
JEFA Tech Low Loss 240 FLEX is ideal for portable operation when small cable size and flexibility is important. It has signal lower loss and is more flexible as compared to Low Loss 195. It has an overall outside diameter of 0.154 inches. It features a stranded copper center conductor which will not break under repeated motion and provides greater flexibility, a foam dielectric and double shielding for low signal loss and interference rejection, and a UV protected, Polyethylene jacket.

Low Loss 400 Cable Assemblies
JEFA Tech Low Loss 400 is the most popular "workhorse" cable of the wireless LAN industry. It has a perfect balance of flexibility and low signal loss. Low Loss 400 is the most popular feed line for permanent installations. It has a 0.405 inch outside diameter and features a solid center conductor for greatest performance, foam dielectric and double shielding for low signal loss and interference rejection, combined with a direct burial capable, UV resistant Polyethylene jacket.

Low Loss 400 FLEX Cable Assemblies
JEFA Tech Low Loss 400 FLEX is recommended for applications where the coax cable will be in motion, for example, beam antennas that are on a rotator, short patch cables to go from your patch panel to radio equipment, or mobile applications such as land vehicles, boats and ships. Low Loss 400 FLEX has the same dimensions as Low Loss 400, but it features a stranded copper center conductor which will not break under repeated motion, a foam dielectric and double shielding for low signal loss and interference rejection, and a UV protected Thermoplastic Elastomer Jacket which is soft and flexible as compared to a Polyethylene Jacket. It is not recommended for direct burial.

Low Loss 600 Cable Assemblies
JEFA Tech Low Loss 600 is for installations were the lowest amount of signal loss is required. With a 0.59 inch diameter, Low Loss 600 is much larger and stiffer than 400, but it has the lowest signal loss rating of all of our cables and will give you the best performance. It features a solid center conductor for greatest performance, foam dielectric and double shielding for low signal loss and interference rejection, combined with a direct burial capable, UV resistant jacket.

JEFA Tech RG Series Coax

RG-8X Cable Assemblies
For the Amateur Radio market, JEFA Tech RG-8X is ideal for HF and VHF portable operation when small cable size and flexibility is important. RG-8X is great for portable operations when a high performance, yet light and flexible cable is required. It is the same cable as our Low Loss 240 Flex. Why one cable with two names? It has signal lower loss and is more flexible as compared to Low Loss 195. It has an overall outside diameter of 0.154 inches. It features a stranded copper center conductor which will not break under repeated motion and provides greater flexibility, a foam dielectric and double shielding for low signal loss and interference rejection, and a UV protected, Polyethylene jacket.

RG-213/U Cable Assemblies
JEFA Tech RG-213/U is a very flexible, low loss coax cable which is ideal for HAM Radio HF and CB use. It is suitable for mobile applications, and it can also be used around a rotator. It features 7 x 0.752 inch bare copper strands to form the center conductor, a solid polyethylene dielectric, a 95% bare copper braid, and an overall diameter 0.405 inch PVC jacket.
