ON4UN uses a single elevated radial on 80 over his extensive
non-resonant 160 meter radial system.

Mose elevated radial systems seem to work better with a "choke
'balun'" to reduce ground currents on the shield.

It depends on what purpose the radials serve. Elevated radials
become part of the radiating antenna (see ON4UN page 11-55) and
generally need to be tuned.

Elevated radials should be resonant. They effect the resonant
frequency and bandwidth of the system.
