So that's why the CFA works miracles for its inventors and merely acts like a short vertical for everyone else. We're not true enough believers in magick....
Dear Peter, "Could I ask what vector potential is?" - Thank you for asking! I spent many years asking the same question and the usual answer that I got was that it was something to do with fluid mech
The loading coil is not just a matching device, it is also a primary source of vector potential and it is the vector potential, rather than its offspring, the magnetic and electric fields, which is
I have just read some recent correspondence on this net concerning the pros and cons of placing the antenna loading coil in the shack or at the base of the vertical aerial wire. The loading coil is n
and should have added (?): If it is cooled down too far below zero the winding maybe superconducting and current might be so high that the receiver could be damaged? 73, LA8AK http://home.online.no/~

Chris Most of your losses will normally be in your ground system - not the loading coil. Amateur LF vertical antenna systems of necessity have severely constrained (size/efficiency) ground systems. S
Andy, what you say requires intelligence to be done. Intelligence nowadays is a scarce resource, and it is more and more made optional. Who needs it ? When the red lamp glows, just push the yellow bu
