The Diamond X200N is a premium, professional-grade dual-band base station antenna precision-engineered in Japan by Diamond Antenna. Designed for high-performance transmission and reception across the VHF (144 MHz) and UHF (430 MHz) bands, this heavy-duty vertical antenna is the definitive choice for commercial radio networks, emergency services, and demanding amateur radio base stations.
Constructed with high-strength fiberglass, the X200N features a linear multi-element phased architecture—utilizing a $2 \times 5/8$-wavelength configuration on VHF and a $4 \times 5/8$-wavelength configuration on UHF. This advanced design delivers a high-gain profile ($6.0\text{ dB}$ on VHF / $8.0\text{ dB}$ on UHF), focusing the radiation pattern toward the horizon for maximum long-range propagation and exceptional signal penetration. Engineered to withstand harsh outdoor deployments, it boasts a wind survival rating of up to 50 meters per second.
