NEC2 model of 40m loaded cubical quad
Hi - I am trying to play around with modeling a loaded 40 meter
cubical quad. To start I made a single loop the size I wanted (about
2/3 full size) - I then looked at the impedance on 7.1Mhz. I added a
load (inductance) to bring the loop to resonance on 7.1Mhz. I then
created some parasitic elements - a director and reflector. I used the
same value load for these elements. Now, can I just adjust the lengths
of the wires to tune the feedpoint impedance and directivity and leave
the value of the load alone? Or is there some reason I will need to
adjust those values too? I placed the load opposite the feedpoint,
FYI.
