Details may be published later, but in a nutshell the antenna may be fed in Common Mode as a "T" vertical against elevated radials OR it may be fed in Differential Mode as a resonant Dipole. In addition the antenna will be made to work on both 160 meters and 80 meters. On 80 meters especially, the feed will be at a high impedance which is the reason for the big insulators. The antenna will begin life as a vertical on 160 meters only - it´s primary function - other modes will be activated next summer when the weather is better. TF3DX is an electrical engineer/professor at the University of Iceland and he has been working on the design for two years. A month or so of number crunching CPU time has gone into modelling the antenna with EZNEC Pro5. One day I will have time to make a map of my antennas. The antenna is a design by TF3DX.

This “KING” antenna is a Vee-beam, or rhombic?
Do you have a Map of your antenna property? Can you publish it?
