Digital 549EW-RS 8' Tapered Extension with Rupp Collar

The Digital 549EW-RS 8' Tapered Extension with Rupp Collar is a professional-grade antenna extension designed for mobile and base station radio systems in law enforcement, emergency services, and tactical field operations. This extension lengthens overall antenna coverage and signal transmission capability, making it an essential component for operators who require enhanced communication range and clarity in remote or high-RF-interference environments. The pre-installed Rupp collar provides immediate compatibility with standard antenna mounts, eliminating setup delays in time-critical deployments.

Built from heavy-duty fiberglass with stainless steel ferrules, the 549EW-RS delivers robust durability in demanding field conditions—resist UV degradation, saltwater corrosion, and mechanical stress from vehicle mounting vibrations and transport. The tapered design reduces wind loading and harmonic resonance while maintaining structural integrity across temperature extremes. Both the 1"-14 threaded top and base connections meet industry standards, ensuring seamless integration with existing Digital Antenna systems and aftermarket mounts. The high-gloss urethane finish provides additional weather protection and extends service life in harsh outdoor environments.

This extension is ideal for mobile command vehicles, tactical support units, and field teams requiring longer-range VHF/UHF communication without installing a full-length permanent antenna. It suits operators using trunk mounts, magnetic mounts, or fixed roof installations where antenna height can be increased to improve propagation. At 3 lbs, the assembly adds minimal weight burden while delivering measurable signal gain over shorter extensions. Installation is straightforward—simply thread onto compatible Digital Antenna bases or extensions with matching 1"-14 connections, secure the Rupp collar, and verify torque specs per manufacturer guidance for optimal electrical performance.
