Chelegance KC4 4-Band HF Vertical Base Antennas are versatile and powerful 4-band HF vertical antennas designed for base station use covering the 40m, 20m, 15m, and 10 meter bands and provide the operator seamless multi-band operation with automatic band switching. With its power handling capacity of up to 1000W PEP (500W CW and 300W Digital modes), the KC4 ensures reliable performance across various modes, including SSB, CW, RTTY and other digital modes. Its top-loading design enhances efficiency, while the self-supporting vertical radiator eliminates the need for ground radials, simplifying installation. The antenna stands at 25.60 ft. tall and is built to withstand harsh weather conditions, making it a reliable choice for both casual and serious operators. Final tuning and trimming is necessary to achieve the lowest SWR.
