The Moonraker AMPRO-15 is a high-performance, helical wound mobile HF antenna specifically engineered to deliver efficient, narrow-band signal propagation across the 15-meter amateur radio band. Designed to overcome the physical limitations of vehicular installations, this heavy-duty whip balances a optimized physical clearance profile with excellent electromagnetic radiation characteristics. It serves as an essential mobile tracking asset for field teams, emergency communications operators, and overland fleet vehicles requiring stable point-to-point high-frequency voice or data links while in transit.
The internal architecture utilizes a precision-wound helical wire configuration on a durable fiberglass mast to achieve electrical resonance at 21 MHz. This design allows the antenna to reach an operational length of 200 cm while maintaining a highly efficient radiation pattern. Optimized for peak performance, the AMPRO-15 offers a targeted operating bandwidth of 200 KHz paired with an impressive voltage standing wave ratio (VSWR) of 1.5:1 or better at the center frequency. This precise matching safeguards your transceiver’s final power amplifier stage from reverse-power thermal strain during intense transmission cycles.
Built to endure the mechanical stress of highway wind resistance and rugged terrain vibrations, the antenna base features a high-retention, industry-standard 3/8×24 threaded male fitting. This heavy-duty structural connector ensures an easy, secure layout into heavy bumper mounts, roof brackets, or gutter clips. Fully adjustable for exact fine-tuning on the workbench or in the field, this turnkey mobile antenna kit comes complete with a custom hex key and an English instruction guide, ensuring immediate out-of-the-box field deployment readiness for your radio communication fleet.
