Diamond VX-30N Dual Band 2m & 70cm Ham Base Antenna, No Radials, 2.15/5.5dBi Gain, 150W, N-Type, 1.3m

The Diamond VX-30N is a compact, radial-less dual-band fibreglass base station antenna for 2-metre (144 MHz) and 70cm (430 MHz) amateur radio use — ideal for both digital (DMR, D-STAR, Fusion) and analogue operation. The no-radials design makes installation clean and straightforward, with no ground plane or radial wires to configure. With a gain of 2.15 dBi on 2m and 5.5 dBi on 70cm, 150W FM power handling, and a VSWR of less than 1.5:1, it delivers excellent omnidirectional performance on both bands from a single compact 1.3m antenna. The N-type connector ensures low-loss, weatherproof connectivity. FRP (fibreglass) outer shell for durable outdoor performance. Rated to withstand wind velocities of 60 m/s. Mast mounting brackets included for masts of 30–62mm diameter.
