1. Introduction
This manual provides essential instructions for the proper installation, operation, and maintenance of your Workman Magnetic Mobile Antenna. Please read this guide thoroughly before using the product to ensure optimal performance and longevity.
2. Product Overview
The Workman Magnetic Mobile Antenna is designed for amateur ham radio use, specifically for the 2 Meter (VHF) and 70 cm (UHF) bands. It features a magnetic base for easy mounting on metallic surfaces, a flexible whip antenna with a loading coil, and an integrated coaxial cable with a PL-259 connector.
Key Features:
- Dual-band operation for 2 Meter (140-160 MHz) and 70 cm (430-470 MHz) amateur radio bands.
- Magnetic mount for secure and temporary attachment to vehicle roofs or other metallic surfaces.
- Approximately 12 feet of high-quality coaxial cable for flexible placement.
- Equipped with a standard PL-259 connector for compatibility with most ham radio transceivers.
- Black finish.

3. Setup and Installation
- Antenna Placement: Select a flat, metallic surface on your vehicle, such as the center of the roof, for mounting the antenna. Ensure the surface is clean and free of debris to maximize magnetic adhesion and provide a good ground plane. Avoid placing the antenna near other metallic objects that could interfere with its performance.
- Cable Routing: Carefully route the coaxial cable from the antenna to your radio. Avoid pinching the cable in doors or windows, which can damage the cable and affect signal quality. Ensure the cable is not exposed to excessive heat or sharp edges.
- Connector Connection: Connect the PL-259 connector at the end of the coaxial cable to the antenna input port on your ham radio transceiver. Ensure the connection is secure but do not overtighten.
- SWR Check: Before transmitting, it is highly recommended to check the Standing Wave Ratio (SWR) using an SWR meter. An SWR reading of 1.5:1 or lower is generally acceptable. High SWR can indicate an issue with the antenna, cable, or placement, and can potentially damage your radio's final amplifier.
4. Operating Instructions
Once installed, the Workman Magnetic Mobile Antenna is ready for use with your dual-band ham radio transceiver. It is designed to operate efficiently on both the 2 Meter (VHF) and 70 cm (UHF) amateur radio bands.
- Ensure your radio is set to the correct frequency within the antenna's operational range (140-160 MHz for 2 Meter, 430-470 MHz for 70 cm).
- Always perform an SWR check when changing frequencies significantly or if you suspect a performance issue.
- For optimal performance, operate the antenna on a large metallic surface that acts as a ground plane.
5. Maintenance
Regular maintenance helps ensure the longevity and performance of your antenna.
- Cleaning: Periodically clean the magnetic base and the mounting surface to ensure a strong, secure connection and prevent corrosion. Use a soft cloth and mild cleaner.
- Cable Inspection: Inspect the coaxial cable for any signs of wear, cuts, or kinks. Damaged cables can lead to signal loss and increased SWR.
- Connector Check: Ensure the PL-259 connector remains tightly secured to your radio. Loose connections can degrade performance.
- Antenna Whip: Check the antenna whip for any physical damage or bending.
6. Troubleshooting
If you experience issues with your antenna, consider the following troubleshooting steps:
- Poor Signal / High SWR:
- Verify all connections are secure, especially the PL-259 connector.
- Ensure the antenna is mounted on a clean, flat metallic surface providing an adequate ground plane.
- Inspect the coaxial cable for damage.
- Test the antenna with a different radio or cable if available, to isolate the problem.
- Antenna Not Sticking:
- Clean the magnetic base and the mounting surface thoroughly.
- Ensure the mounting surface is metallic and flat.
