Diamond X-50N Dual Band 2m & 70cm Ham Base Antenna 4.5/7.2dBi Gain, 200W, N-Type, 1.7m, Pre-Tuned

The Diamond X-50N is a mid-range, high-performance dual-band fibreglass base station antenna for 2-metre (144 MHz) and 70cm (430 MHz) amateur radio use — sitting between the compact X-30N and the larger X-200N in the Diamond dual-band range. With a gain of 4.5 dBi on 2m and 7.2 dBi on 70cm, 200W power handling, and a 3 x 1/4 / 3 x 5/8-wave collinear design, it delivers excellent omnidirectional performance on both bands from a 1.7m antenna. Pre-tuned and fully weatherproofed fibreglass construction with mast mounting brackets included. The N-type connector ensures low-loss, weatherproof connectivity. Rated to withstand wind velocities of 60 m/s. Mounts on masts of 30–62mm diameter.
