Diamond Antenna Duplexers are just what you need when splitting HF, VHF, or UHF signals. They are ideal for connecting HF/VHF radios, such ICOM IC-706 and IC-7000 series, and Yaesu FT-857 series, with two antenna ports, to a single feedline multi-band antenna, like the Diamond V7A. Diamond Antenna Duplexers eliminate the need to use an antenna switch and are made with a high-quality aluminum case with a black finish.
