The Diamond SE-100 is a high quality dual band VHF/UHF vertical antenna designed for marine use, but equally suitable for land-based installations where a discreet, radial-free antenna is required. Covering 2m and 70cm, it provides reliable omni-directional performance for amateur radio operation on 144 to 146MHz and 430 to 440MHz.

Unlike Diamond’s well-known X series antennas, the SE-100 has no radials, making it ideal for environments where protruding elements may get in the way, such as boats, masts, balconies or compact installations. Its metal parts are designed to better withstand saltwater spray and harsh environmental conditions, with stainless steel hardware and protective coatings used throughout.

The antenna features a permanently attached brass and chrome plated mounting tube fitted to a white glass fibre radome, giving it a clean, unobtrusive appearance. With up to 6dBi gain on 2m and 8dBi gain on 70cm, the SE-100 is a strong choice for operators needing a durable, neat and weather-resistant dual band antenna.
