Over 6 years ago, DX Engineering introduced the patented (US Patent No. D534,905) serpentine style end insulators (DXE-UWA-END-KIT) which are custom molded from high impact fiberglass impregnated nylon for tremendous breaking strength and UV protection. Since then, thousands of the DX Engineering End Insulators have been installed around the world.
The End Insulators were specifically designed to provide a strong wire gripping method by routing DXE Engineering Antenna Wire (DXE-ANTW series) through a series of slots in a serpentine manner. This allows easy, one-step length adjustment for tuning a dipole without having to terminate the wires.
DX Engineering Antenna Wire is a 14 gauge, 19 strand copper wire with a black ‘relaxed’ PVC insulation. This means the wire remains flexible, lays out flat and won’t coil up when tension is removed. This wire has been proven to be superior for dipole antennas and has consistently provided years of service without any problems.
