KLM’s 4 element 40 meter "Big Sticker" has constant gain and low VSWR across the entire 40 meter band. Its broad band characteristics and the clean pattern are achieved through two properly phased driven elements. The load impedance is 200 ohms and can be matched to 52 ohm coax with a 4:1 balun. Element shortening (maximum length of any element is 47 feet ) is acheived through use of tubular linear loading sections with permanent, low loss characteristics. The folded-back loading sections are positioned on either side of an element-and extended out about half way either side of center. Outer element sections bear no extra weight so can be smaller in diameter, lighter, and have less tendency to droop. Because of the unique positioning of the linear loading, extremely close stacking may be used with 20 meter beams without degrading performance of either Antenna.
