Worked with A.J. to get a custom length dual lead SMA extension cable. Communication was great and I am quite satisfied with the experience. A.J. knew exactly what device I was connecting to and guided me to the exact cable I needed. Thanks again!Mike Thomas

I have had Jefa Tech coax cables in service now for several years. They have survived very well in an extreme environment. I typically budget for and expect to replace cables about every 6 months. The only cables that have not required replacement are the Jefa Tech. They are still performing perfectly with no water infiltration, no shielding, insulator or jacket degradation. Performance specs are still intact. So far with how these cables are holding up, I expect several more years of service from them. The pricing, in my opinion is very good considering the performance and service life, they are a very good value. Customer service at Jefa Tech is absolutely the best I have ever experienced anywhere, period. I recently ordered cable and had a minor issue with it. This was cleared up immediately, they went over and above what would be expected. From my experience with Jefa Tech products they are equal to and in some cases better than other brands currently on the market. For cost, quality, and customer service I highly recommend Jefa Tech!S Young

Repaired and tested a bunch of RG 213 coax cables our Amateur Radio Club had. We had to have a few dozen pl259 reinstalled to make the coax operational again. They did an exceptional job with a great turnaround time.Chris WheelerSt. Mary's County Amateur Radio Club

I've bought several custom-made coaxial cables from Jefa Tech to use with my various amateur radio applications. They have always sent me cables made with the highest quality materials and workmanship, and with very fast shipping. They will be my go-to supplier for cables, and will be looking at their other products, as well.Bill Robie
