The recently upgraded, computer optimized, linear loaded, dual driven 40M4LLDD-125 gets the bandwidth and maintains performance across the band like no other 40 meter Yagi. This was a huge challenge requiring the latest techniques in computer optimization. Gain, Front to Back and VSWR are maintained nearly flat across the whole band! In addition, it is now better mechanically and easier to assemble. Only the tips of each element are different as all the linear loading settings are the same for each element. The shorting bars are now 2 piece, clamp type making solid long lasting connections. For foreign amateurs, two tuning options are available; FULL BAND and LOW END ACCENTUATED, 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 crossband SSB contesting needs and give you years of enjoyment on the 40 meter band regardless of future band plan changes. Mechanically, the elements are sleeved double and triple wall to withstand continuous winds of 125 mph or the constant battering of high winds and ice months at a time. This antenna WILL frustrate Mother Nature! The Driven elements are split in the center and insulated with a solid 1-1/4 fiberglass rod. The parasitic element also have solid 1-1/4 center aluminum center section. The 3 kW continuous, 5 kW peak, 1:1 balun completes the package. All hardware is stainless or galvanized except the U-bolts.
