And yes....DX Engineering does offer very good coax. I have purchased several hundred feet of their LMR400 Ultra Flex pre-made assemblies with the PL259 connectors (in varying lengths of course) over the years. I currently have two runs of their 400Flex feeding a couple of antennas in the yard right now. Good quality products and coax they sell as well. I really like their LMR 400 and their PL259's. But for some custom applications with specific connectors and lengths of varying coax.......Antenna Farm is where I usually go. Just my preferences.
