144/430MHz VHF UHF Dual Band Base Station Antenna X200 6/8dBi – Fiberglass Vertical Antenna
The X300 is a dual-band VHF/UHF base station antenna designed for stable and extended-range communication in 144 MHz and 430 MHz frequency bands. Featuring a high-gain collinear structure (6.5 dBi @ 144 MHz, 9.0 dBi @ 430 MHz), it delivers enhanced signal strength and reliable omni-directional coverage for fixed station installations.
With a low VSWR (≤1.5) and 50 Ohm impedance, the X300 ensures efficient power transmission and reduced signal reflection, supporting a maximum input power of 200W. The antenna is vertically polarized and constructed with a durable fiberglass radome and copper radiating elements, providing strong weather resistance and long-term outdoor stability.
Standing at 3.1 meters in height and available with SO239 or N-Female connectors, the X300 is suitable for amateur radio base stations, repeater systems, emergency communication networks, and industrial wireless applications. OEM customization is available to meet specific project requirements.
