The Diamond X-200N 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 — one of Diamond's most popular and well-regarded dual-band base antennas. A significant step up from the compact X-30N, the X-200N 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. The N-type connector ensures low-loss, weatherproof connectivity. Fibreglass and stainless steel construction for long-term outdoor durability. 200W power handling. Ideal for fixed home stations, repeater links, and operators who want the best dual-band base performance from a single antenna.
