This is a much better antenna than the fixed height 43' vertical that is
so popular.

Jim. The bigIR can be tuned to a quarter wave on all frequencies from 7 to
54 MHZ. On frequencies from 21-54 MHz you can select a 3/4 wavelength
mode.
I have used this antenna with raised radials, tuned stub radials and a
ground mounted radial field. Works well in all cases. It is still a
quarter wave vertical.
No magic
