The Diamond A144S10R2 is a professional-grade, high-gain 2-meter VHF Yagi beam antenna engineered to deliver exceptional directional signal projection and long-range communication tracking. Featuring an advanced 10-element array, this premium directional antenna is highly optimized for operators looking to establish long-distance point-to-point links, satellite downlinks/uplinks, or clear simplex base station networks. Unlike complex multi-element kits that demand intricate field calibration, the A144S10R2 arrives completely factory adjusted, dropping the need for tedious manual tuning or specialized SWR instruments during setup.
The physical structure is designed for swift, straightforward assembly, allowing fieldwork teams or hobbyists to deploy the array in minutes. Built using durable, lightweight aluminum elements, the antenna handles environmental outdoor stress while keeping a total weight of just 1.1kg. With geometric dimensions measuring 2,130 x 1,090 x 73 mm, its optimized boom length provides an excellent balance between high forward directionality and physical wind-load management, making it easy to mount on lightweight mast configurations.
On the electrical layer, the A144S10R2 operates smoothly within the 144 to 146 MHz frequency band, offering a commanding forward gain of 11.6dB to pierce through heavy line-of-sight path loss. It features a continuous power threshold rating up to 50W FM, making it fully compatible with standard VHF mobile transceivers and base stations. Equipped with a rugged, low-loss female SO-239 UHF (MJ) connector block and standard 50 Ohm nominal impedance, this turnkey Yagi antenna ensures immediate out-of-the-box fleet readiness for your communication infrastructure network.
