FEATURES:
Recently, M2 engineers developed a new way to make coils using CNC tooling. The result is a precision inductor increasing Q and lowering loss to new levels. A coil loaded Yagi design was computer optimized, and not one single change was required on the finished Yagi. This design gets the bandwidth and maintains performance across the band like no other 40 meter Yagi. Gain, Front to Back and VSWR are maintained nearly flat across the 7.0 to 7.2 MHz band section.
Mechanically it is easy to assemble. Only the tips of each element are different as all the coils are the same for each element. The coils themselves float in air minimizing dielectric loss. They are fully covered with a husky polyethylene cover. Each end of the coil uses a massive 3.75” full circumference solid connection. Two tuning options are available; 7.0-7.2 or 7.1-7.3 but still broadband. The resulting design is head and shoulders above the competition in strength, durability and performance. This antenna has been designed to meet your contesting needs and give you years of enjoyment on the 40 meter band. Remember foreign broadcast is now gone below 7.2 MHz and foreign hams can now transmit all the way to 7.2 MHz on phone and CW. 40M is now a spectacular worldwide DX band! If you haven’t tried 40M lately, you are in for a treat! Mechanically, the elements are identical to it’s older brother, the 40M4LLDD. The 40M4CDD can also withstand continuous winds of 100 mph or the constant battering of high winds . This antenna too, WILL frustrate Mother Nature! The 3 KW PEP, 1:1 balun completes the package.
