Model No: 40M3L
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 1:1
balun. All elements use linear loading of 3/16" 6061-T6 aluminum rod to reduce overall length, wind load, and
turning radius. The linear loaded sections anchor 10" above the element to reduce inductive cancellation
(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!). Compare performance, construction and durability....
This is not
just another 40 meter Yagi!!
