Momobeam TRI9 30/17/12 Meter Full-Size Yagi Antennas

Momobeam TRI9 30/17/12 Meter Full-Size Yagi Antennas are the perfect choice for operators who appreciate the unique characteristics of the WARC bands. These antennas offer medium overall dimensions while maintaining full size elements across all three bands, ensuring optimal efficiency and strong on air results. The design features four elements on 24 MHz, three elements on 18 MHz, and two elements on 10 MHz, delivering excellent gain, bandwidth, and pattern control on each band.

Engineered for consistent, high quality performance, TRI9 30/17/12 antennas provide a flat SWR curve with values under 1.5:1 across all three WARC bands without requiring additional tuning. Their electrical performance allows operators to break through demanding pileups with confidence, giving the station a significant advantage during DX openings and rare entity activations.

Each TRI9 30/17/12 antenna includes an assembly tool and spare parts such as bolts and an aluminum tube, offering convenience and long term serviceability. A high quality 3kW RF choke balun is supplied as standard—a premium component that many manufacturers offer only as an extra-cost option. This balun helps maintain clean RF behavior, reducing unwanted feed line currents and improving overall system performance.

Assembly is designed to be simple, fast, and intuitive. The antennas use a square boom structure, and all hardware arrives in individually labeled bags. Every aluminum tube is clearly marked to ensure accurate placement, making the installation process smooth and error free even for first time builders.

Requiring a medium to heavy duty rotator, the TRI9 30/17/12 Meter Yagi Antennas combine mechanical strength, refined electrical engineering, and user friendly assembly. They deliver outstanding performance for WARC enthusiasts who want powerful, dependable antennas without excessive footprint or complexity.
