My first suggestion would be to use a terminated folded dipole cut large
enough for 80m and the rest would just work. Have a look at Mr Cebik's
website for details.

Good morning, Bob.

Wouldn't the terminated folded dipole be too lossy at the lowest
frequencies of interest?

In any case it looks like a terminated folded dipole would cost at
least a full "S" unit over a dipole, at any frequency (and much more
than that down by the low end of the design range).

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? There would be a single wire on the "fed" side of the
loop, tapped off at points along its length to create anchor points
for the other three sides of a loop for each frequency.

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

CJ
