DX Engineering 400MAX Low-Loss 50-ohm Coaxial Cable Assemblies are premium, low-loss coaxial cable assemblies with a special Type III-A, UV-resistant polyethylene jacket that is waterproof; ideal for outdoor feedline applications, particularly direct-bury. With its larger 10 AWG stranded copper center conductor, 400MAX is specially suited for high-power amateur stations, providing a lower loss solution for long cable runs at any power level. The high-quality construction continues with a gas-injected foam polyethylene dielectric, followed by the highest level of shielding from bonded aluminum tape covered by a tinned copper shield braid.
DX Engineering 400MAX Low-Loss 50-ohm Coaxial Cable Assemblies are complete with high quality silver plated PTFE dielectric PL-259s. Their machine crimped shields feature 360 degrees of complete mechanical and electrical contact for maximum reliability. Their center conductors are hand soldered and inspected. All DX Engineering Cable Assemblies are Hi-Pot tested and heat-shrink weather-sealed for the ultimate in service longevity.
