The Diamond X-200 is a high-gain, dual-band fibreglass and stainless steel base station antenna for 2-metre (144 MHz) and 70cm (430 MHz) amateur radio use — the SO-239 version of the popular X-200N. One of Diamond's most well-regarded dual-band base antennas, the X-200 delivers 6 dBi gain on 2m and 8 dBi on 70cm from a 250cm collinear design with 3 radials, providing noticeably greater range and signal strength on both bands compared to shorter dual-band antennas. Fibreglass and stainless steel construction for long-term outdoor durability. 200W power handling. Connects via SO-239 (UHF-Female). Ideal for fixed home stations, repeater links, and operators who want the best dual-band base performance from a single antenna.
