Coax Seal is a rubberized mastic tape that you apply outdoor coax connectors after installation. It fully seals the connection from weather and prevents moisture from entering the cable and corroding it from the inside out. If this assembly will be installed outdoors, this option is recommended.
We can add custom printed white heat shrink labels with black lettering to your custom coax cable. Cost is per cable and includes two labels, one label on each end of the cable.

    LL-400 Cable

    Jefa Tech cable is as good as it gets. I’ve had LL-400 direct burial cable in the ground for 10 years now and still working like it should.

    Great product and customer service

    I got my ham radio license a year ago and read a comment online about Jefa and bought this coax along with angle connectors and I couldn’t be happier with the performance. Living in nw Ohio the weather is always changing but this LL-400 has held up. Now my 2nd antenna will be going up and I’m gonna go with the LL-600 for that one.

    Great!

    From jumpers in my shack to 100 ft feed line, these guys make a super-high quality product to your specs really fast. Best company for cabling hands down. Excellent value for amateur radio operators.

    coax cable

    I knew that I went with the right company when coax was needed. I currently have Jefa tech cable in service now that has been in extremely harsh environments for years. This cable is still performing very well and has out lasted all other brands. Your company will always receive the top reviews and recommendations from me. Thanks again
