Diamond A1430S8 Dual Band Beam Antenna 2m/70cm, 9/10dBi, 3+5 Element, 100W

Diamond A1430S8 Dual Band Beam Antenna

The Diamond A1430S8 is a dual band directional beam antenna for the 2m (144MHz) and 70cm (430MHz) amateur radio bands. Combining a 3-element Yagi on 2m with a 5-element Yagi on 70cm, it delivers 9.0dBi gain on 144MHz and 10.0dBi on 430MHz — ideal for weak signal work, satellite operation, direction finding, or boosting range from a fixed base station. Compact enough for a 1.35m turning radius, it suits smaller rotator setups.
