Requires ¼ wave radials for each band or many (60+) short radials. Since the antenna needed to be vertically polarized, I hit upon the notion of a J-pole. What these numbers have in common is the belief that the feedpoint is the 300-ohm point along the antenna element. Radials must be tight, one end insulated, the other one fixed at the antenna base (in fact to the mast, the gray tube) to be efficient as their are fully integrated in the antenna design.
