For the last few years I have just been matching my topband vertical
or inverted L antennas by using a 1:4 UNUN
I have just seen the following article by Jay at Array Solutions..
where he resonates the antenna at 1.9MHz which gives a capacitive
reactance at 1.83 (which becomes a phantom part of the L-network) the
other part being a real inductance to earth. I like the look of this
arrangement because of its simplicity and the fact that there is a DC
connection to ground.
I would like to try and model this directly in EZNEC, but not quite
sure how to define the load components and the source in this case.
1) Can I just specify a load of L+R (where R is the simulated earth
loss) and the source in the lowest segment?
2) Should I put the L+R in the lowest segment and the source in the
next segment up?
3) Or is there a better way?
I would appreciate any advice from anyone with a bit more experience
than I have.
