The Diamond X-300 is a premium high-gain dual-band fibreglass base station antenna for 2-metre (144 MHz) and 70cm (430 MHz) amateur radio use — the big brother to the popular X-200 N, delivering even greater gain from a longer 3.1m collinear design. With 6.5 dBi gain on 2m and an impressive 9 dBi on 70cm, the X-300 is one of the highest-gain dual-band base antennas in the Diamond range, making it the ideal choice for operators who want maximum range and signal strength on both bands from a fixed station. The 2 x 5/8-wave (2m) and 5 x 5/8-wave (70cm) collinear design provides excellent omnidirectional coverage. Pre-tuned and fully weatherproofed fibreglass construction. 200W power handling. 52cm radials. Mounts on masts of 30–62mm diameter. Wind rated to 50 m/s.
