FEATURES:
The 40M2C is the latest addition to our already exceptional 40 meter Yagi lineup. Using all the latest design and manufacturing tools,
including 3D printed coil forms. Our coil loaded antennas now make it difficult to choose a full size equivalent. Mounting this Yagi at 70
feet creates incredibly clean pattern with unique front to rear and above performance.
Our new covered coil design features 3/16" diameter copper clad soft drawn aluminum that has great power handling and high efficien-
cy (Q over 900) combined with low weight. We use 3D printing for precision coil forms. The coils are located at the optimum place in
each element half. The location of the coil is important for best performance and this careful placement also breaks the element into
small electrical lengths that appear shorter than 20 meter elements. This means there is little or no interaction with any 20 meter Yagi
on the same mast OR on the same boom. Our new DUAL BAND "CYCLE BUSTER " takes full advantage of this unique feature.
Mechanically, the coil loading offers a cleaner look with less wind area and fewer connections. Wind and ice loading are reduced as
well. We continue to offer the same unbreakable element mounting and OVER HEAD element support. The rugged, time tested ele-
ments and 3 kW 1:1 Balun are part of the package. All Hardware is stainless steel except for the Galvanized U-bolts and saddles.
(Stainless U-bolts tend to Gall and freeze up) and used in our other 40M Yagis.
