Twenty meter contesting stack consists of five 4-element 20 meter G0KSC OWA yagi's. The lower four antennas are fixed in four directions and the upper antenna is rotatable. The stack allows one to spray a pattern in multiple directions plus combine any antenna with the top rotatable antenna for stacking gain. The homebrew antenna switching controller allows selection and matching of up to 8 antennas. Similar stacks for 15 and 10 meters are in-process. The antennas are all homemade and use heavy duty DX Engineering DXE-SAD series saddle clamps. de AB5K
