Momobeam Duo4 12/17 Dual Band HF Yagi Antennas are designed for the 12-meter and 17-meter WARC bands. Despite its very compact dimensions, it features full-size elements for superior efficiency. A unique aspect of this antenna is its innovative “open sleeve” feed for the 24 MHz driver, which eliminates the need for a direct connection and greatly simplifies assembly. The Duo4 delivers low SWR on both operating bands, making it an ideal match for modern transceivers and linear amplifiers.

Assembly is simple and intuitive thanks to its square boom design, clearly labeled aluminum tubes, and hardware supplied in separate, marked bags. The antenna requires only one coaxial cable and a rotor for a small load, ensuring easy installation and reliable performance. Perfect for operators seeking exceptional signal quality in a compact footprint, the Momobeam Duo4 combines convenience, durability, and outstanding results for serious HF enthusiasts.
