Wt... 90 LBS / 99 LBS / Truck or Air FEATURES The 40M3L is a linear loaded 40 meter Yagi designed with 20 years of experience and listening to customer's needs. The result is a powerful package of clean mechanical design, quality materials, and outstanding performance that will deliver years of enjoyment on the 40 meter band. Mechanically the elements are mounted between 1/2" thick, machined aluminum clamp plates! The Driven element is split and insulated with a 1-1/4 inch solid fiberglass rod and fed with a weather sealed coaxial 1:1 balun. All elements use linear loading of 3/16" 6061-T6 aluminum rod to reduce overall length, windload, and turning radius. The linear loaded sections anchor 18" above the boom to reduce inductive cancelation (requiring LESS loading), reduce mechanical stress, and minimize element droop (in the air the antenna is easily mistaken for a 15 or 20 meter Yagi!). All hardware except U-bolts is stainless steel. Compare performance,
