Diamond X-30 Dual Band 2m & 70cm Base Antenna 3/5.5dBi Gain, 150W, 1.3m, Pre-Tuned

The Diamond X-30 is a compact, lightweight dual-band fibreglass base station antenna for 2-metre (144 MHz) and 70cm (430 MHz) amateur radio use — the entry point to the Diamond dual-band base antenna range, sitting below the X-50N and X-200N. At just 1.3m tall and 0.8kg, it's ideal for operators with limited space, balcony installations, or those looking for a discreet, low-profile base antenna without sacrificing build quality. With 3 dBi gain on 2m and 5.5 dBi on 70cm, a 1/2-wave (2m) and 2 x 5/8-wave (70cm) collinear design, and 150W power handling, it punches well above its compact size. Pre-tuned and fully weatherproofed fibreglass construction with mast mounting brackets included. Wind rated to 60 m/s. Mounts on masts of 30–62mm diameter.
