A few years ago I installed lengths of LMR-400 Direct Burial coaxial cable in my back yard. I wanted good connectors for my investment. I seriously considered the superior N connectors, but my DX Engineering Coax Switch uses SO-239 connectors. While not the high quality choice, I succumbed to tradition and sought out suppliers for the PL-259.
Money was really no object since the connector is often the weak link in the system and deserves quality. I just made an investment in 240 feet of LMR-400 cable and wasn’t about to shortchange the connector.
