However, looking through L.B.'s website gave me another idea ... what
about a triband full wave loop similar to what is shown in the
attached JPEG?

Have any of you tried anything like that, and how did it work?


Unlike dipoles, there would be heavy interaction between the
loops on 40m. The feedpoint impedance of an 80m dipole is
very high on 40m and most of the power goes into the 40m
dipole. The feedpoint impedance of an 80m loop is low on
40m so the power is shared with sometimes unexpected results.
You can probably model it with the free demo version of EZNEC
available at www.eznec.com
