Antennas:

The M2 KT36XA is the result of many hours spent on perfecting the original KLM KT-34XA through computer optimization confirmed by range and actual on-air tests. Five elements are active on 20 and 15 meters and all six are working on 10 meters! This is the hottest performing tribander on the market! A dual driven element (log cell) creates a rig pleasing, flat match, and broad gain & front to back curves across 10, 15, and 20m. A 3 kW 4:1 balun efficiently matches the antenna to 50 Ohms.This is the strongest tribander on the market! We probably could have called it the “KB36XA” cuz it does! (“KB” = Kicks Butt).

The STACK of KT36XA's OT4A -ON4AEK wih adjustable spacing (2 elevators on same tower) operationel since July 2012

Night vision of the stack ,see the homebrew 4 el for 40m interlaced with the 5 el for 17 m on the same boom

If you look carefully you can see the 3 el wire beam for 30 m between.
