Dual Band VHF/UHF Mobile Antenna with Magnetic Base

Reliable dual-band vehicle antenna for clear mobile communication

This dual band mobile antenna with magnetic base is designed for drivers, amateur radio users, and field professionals who need consistent VHF/UHF performance on the move. Optimized for the 2m and 70cm amateur bands, it delivers stable communication while remaining compact enough for everyday vehicle use.

Operating on 144/430 MHz, this antenna supports both VHF and UHF, giving you flexibility across commonly used ham radio frequencies. The vertical, omni-directional radiation pattern helps maintain coverage in all directions around the vehicle. With a typical gain of 2.15 dBi (VHF) and 3.5 dBi (UHF) and a VSWR of less than 1.5, it is engineered to provide efficient power transfer and dependable signal quality. The maximum power input is 50 W, making it suitable for most mobile ham radios and many portable setups.

The 3.5 inch magnetic base offers a strong hold on metal surfaces when used with a proper ground plane, so the antenna stays in place even at highway speeds and in windy conditions. The stainless steel whip element provides flexibility and durability for daily use. A 4 m (13 ft) RG-58 coaxial cable with UHF male (PL-259) connector is included, giving you enough length to route the cable cleanly from the antenna mount to your mobile or base radio inside the vehicle. The overall antenna length of about 17 inches allows installation on cars, trucks, and other vehicles without being intrusive.

Why It's a Smart Choice

• Dual-band coverage on 144/430 MHz supports common VHF/UHF ham radio operations in one compact antenna.
• Strong 3.5 inch magnetic base with required metal ground plane enables quick, non-permanent mounting on most vehicles.
• Includes 13 ft RG-58 coax and PL-259 connector for straightforward, plug-and-play integration with compatible mobile and portable radios.

FAQ

Q: Which radios are compatible with this antenna?
A: Any mobile or base radio that operates on 144/430 MHz and accepts a UHF (PL-259) connector is generally compatible. Always confirm your radio's connector type and frequency range before installation.

Q: Does the antenna require a ground plane?
A: Yes. For best performance, the magnetic base should be mounted on a metal surface (such as a vehicle roof or trunk) to provide an effective ground plane.

Q: Can this be used while driving at highway speeds?
A: The magnetic base is designed to remain secure on a clean, flat metal surface under typical highway conditions. Ensure the mounting area is clean and the magnet is seated firmly before driving.

Q: Is any additional cable or adapter needed?
A: The antenna includes a 4 m (13 ft) RG-58 cable with a UHF male (PL-259) connector. If your radio uses a different connector type, you may need an appropriate adapter.
