The serious two meter operator who is interested in EME, aurora, scatter, SSB, CW, tropo etc, will choose the A17B2. It has 17 elements on a 4.5 wavelength boom.
Our computer-aided design supported by precise test range data and the latest manufacturing technology gives you a cleaner pattern and 18 dBi gain in this long boom design. Significant enhancement is provided by the new UltraMatch balanced feed system with N-connector.
The UltraMatch is a modified T-match system that provides a balanced current distribution on your Boomer. It uses UltraLink Teflon® dielectric cable allowing for low loss high power applications. UltraMatch is completely enclosed for weather proofing. When all-weather performance is important, you will choose the new UltraMatched Boomers everytime.
