NOTE: The recommended installation height is 1.5 meters — this is the height we tested near the label position.
KC4 is a 4-band resonant vertical antenna for base station use.
KC4 is designed for seamless multi-band operation. It uses top loading to achieve higher efficiency from a short self supporting vertical radiator. Once set up, you can effortlessly switch between these bands without the need for any adjustments.

KC4 does not require ground radials.
