The Moonraker AMPRO-160 is a high-performance, single-band mobile HF antenna engineered specifically for dedicated operations on the 160-meter amateur radio band (1.8 MHz), commonly known as the “Top Band.” Designed to deliver reliable ground-wave and local sky-wave propagation while on the move, this antenna is the ultimate choice for amateur radio operators looking to bring low-band HF capabilities to their mobile setups. Its streamlined, center-loaded helical design optimizes electrical efficiency while keeping wind resistance to a minimum compared to traditional full-sized whip antennas.
Standing at a total physical length of approximately 200 cm (2.0 meters), the AMPRO-160 features a rugged, flexible fiberglass lower section coupled with a high-efficiency center loading coil. This construction allows the antenna to handle a continuous transmit power of up to 100 Watts, making it perfectly matched for standard 100W HF mobile transceivers. The base of the antenna features a standard, heavy-duty 3/8-inch (3/8″ x 24) male threaded fitting, allowing for secure mounting onto standard heavy-duty vehicle mounts, magnetic bases, or gutter brackets capable of supporting a 2-meter whip.
To ensure peak performance, the AMPRO-160 is designed with an adjustable top stainless steel whip element, allowing operators to achieve a Voltage Standing Wave Ratio (VSWR) of 1.5:1 or better at the resonant frequency (performance varies depending on vehicle grounding and installation location). Because of the physical constraints of operating on the 160m band in a mobile profile, the antenna has an operational bandwidth of approximately 15 kHz. The top whip can be easily adjusted and locked into place using the integrated set screws, giving you precise control over your target operating segment.
