The DIAMOND CP610 – Vertical base antenna / Frequencies 28 (29) / 50MHz / Length 6.8m / Weight 2.9Kg / Gain 3.4dB (28MHz), 5.5dB (50MHz) / Max power 500W (SSB), 200W (FM) / VSWR less than 1.8: 1 nominal / Impedance 50 Ohm / MJ connector / Nominal wind speed 35m / sg / Accepted mast diameter from 30 to 62mm / Type 5/8 (28MHz), 5 / 8×2 (50MHz) is a commercial-grade, high-performance dual-band vertical base station antenna precision-engineered to deliver exceptional long-distance signal propagation and stable communication links. Manufactured by Diamond Antenna, a global benchmark in premium RF hardware, this heavy-duty fixed terminal is optimized for multi-point tracking arrays and baseline command infrastructure. It stands as an essential operational procurement asset for commercial transmission nodes, emergency dispatch centers, amateur radio base configurations, and high-volume B2B radiocommunication equipment wholesale distribution networks looking to source reliable, original factory antenna assets.
The advanced internal RF core of the CP610 delivers specialized dual-band spectrum efficiency, operating continuously across targeted frequencies of 28 (29) MHz and 50MHz (the 10-meter and 6-meter amateur bands). Built to accommodate high-power transceivers and linear amplifiers during dense traffic workflows, the radiator supports a maximum power of 500W (SSB) and 200W (FM). The antenna design leverages highly efficient wave physics configurations, acting as a high-gain type 5/8 wave on 28MHz and a dual-element 5/8×2 wave array on 50MHz. This optimization yields an impressive directional performance with a gain of 3.4dB (28MHz) and 5.5dB (50MHz), significantly lowering angle radiation fields to maximize point-to-point path coverage.
Constructed from premium, heavy-duty weatherized alloys to survive severe structural climate fatigue, the antenna features an impressive total length of 6.8m while maintaining a highly balanced net structural weight of 2.9Kg to minimize physical lever torque on support structures. The mechanical mount base provides exceptional physical compliance, engineered with an accepted mast diameter from 30 to 62mm and certified to withstand a rugged nominal wind speed of 35m/s. Terminated with a high-retention MJ connector (UHF Female SO-239 style) and tuned to maintain a standard impedance of 50 Ohm with a VSWR less than 1.8:1 nominal across the active band cores, this turnkey base antenna guarantees immediate system alignment and absolute multi-season deployment readiness.
