Well, it's probably the Pac-12. Add 1-2 more of those sections to the
part below the coil, use plenty of radials, and try something I saw
someone set up, they just use the 40m coil with a jumper with an E-Z
Hook on it to select turns for higher bands. It's a nice antenna! 73

The whole concept of radials is to improve the conductivity path for return
current to the base of the vertical antenna, when the antenna is not a
complete half wave dipole, (and therefore, balanced and a complete radiator
unto itself). You are replacing always lossy (to some degree), earth or
What Stuart says about radials is quite true, but there is another important
reason for a tuned radial (or other ground connection) other than to improve
the efficiency of an end-fed wire.
Consider the end-fed dipole; it's probably the most extreme example of what
I'm talking about. Fed at the
Good points Ron.
I usually call those RF control radials, an RF counterpoise, as sometimes
you can use one cut for each band of concern and run it around the baseboard
of a shack.
I like to think of a radial as an outside wire, and counterpoise as an
insulated inside the shack RF control aid.
