Shakespeare 5104 4' 3DB VHF Antenna W/15' RG58

The Shakespeare 5104 4' 3DB VHF Antenna with 15' RG58 cable is a field-proven marine and communications antenna designed for reliable long-range VHF reception in tactical, maritime, and emergency response environments. Built to meet the demands of law enforcement, Coast Guard, military personnel, and commercial maritime operators, this antenna delivers consistent signal acquisition across the VHF spectrum. The 4-foot vertical design maximizes coverage while remaining compact enough for vessel, vehicle, and base station installations where space and portability matter.

Construction centers on brass and copper elements that establish industry-standard range and reception performance across VHF frequencies. The antenna features a chrome-plated brass or nylon ferrule with a standard 1-14 inch thread interface, enabling straightforward installation on most marine and tactical communication mounts without requiring adapter hardware. The 15-foot RG58 coaxial cable provides adequate run length from mount point to radio transceiver, minimizing signal loss while allowing flexible equipment placement. The smooth, durable finish resists corrosion and UV degradation—critical factors in saltwater and high-intensity operational environments where equipment lifespan directly impacts mission readiness.

This antenna serves law enforcement marine units, Coast Guard boarding teams, search and rescue operations, and military vessel communications networks. The 3dB gain specification ensures effective transmission and reception at tactical distances without requiring external amplification. Field users appreciate the straightforward 1-14 thread mount, which integrates seamlessly with standard antenna bases found on patrol boats, rescue vessels, command vehicles, and fixed base stations. The included 15-foot cable reduces the need for additional feedline purchases, streamlining deployment. Operators should verify their radio system operates within the VHF band (typically 156–174 MHz) and confirm mount thread compatibility before installation.
