If you want to put up a multiband vertical base antenna for your amateur radio station, but don’t have the space for a robust radial system, the folks at Chelegance offer an excellent solution with the KC4. It’s a 26 foot vertical that’s good for the 40/20/15/10M ham bands and it’ll handle up to 1,000W—with no radials required. In this video from DX Engineering, we’ll show you how easy it is to assemble one of these versatile verticals, and then we’ll give you an honest review of its performance
