This last antenna was Tri-bands 3 elements Cubical Quad Antenna 33 feet high over a small house in Fremont, California, sending and receiving signals to and from around the world. The house with this antenna was actually located one mile away from D.I.'s home and purchased just to install this antenna and his ham radio station - KE6AJ, due to the restrictions set forth by his homeowner's association at his residence. This is the old Tri-bands 2 element Cubical Quad Antenna 10m high at Hwakokdong house, which  D.I. and Jane used to use for HM1AJ and HM1AM  in  Seoul, Korea back in the early 1970s.
