I'd like to thank everyone for their suggestions on how to make my 32'
vertical with 8' elevated loaded radials perform on 80 and 30 meters as
well as 40.
It's clear I will have to do some major surgery on the antenna to add 80
meters, such as a trap plus a toploading wire, or a movable wire

A series circuit resonant at 30 meters will do a good job of shorting out
the 40 meter inductance (no relay) - but the inductor used for 40 meters
would have to be modified to compensate for the effect of the series circuit

I would like to use it on 80m and 30m as well. My first try was to
simply use the KAT100 to tune it. It tunes fine on both bands (1:1 at
the rig), but results are fair-to-poor on 30 and poor-to-worthless on
80.
Can you clarify are the radials elevated
My antenna is similar. 28.5' tall, ground mounted over twelve 28' long
radials. Fed with 30 feet of RG-213. With a tuner the system works
well enough on 40, 30, 20, 15. 80 Meters is the pits. Dummy Load City!
I'm considering putting a remote ATU at the base of the antenna.

Here's an idea that I haven't seen anyone else use, but it might just do the
trick for you.
Lower your vertical and connect a 33 ft piece of good wire at the top. Put
a good
egg insulator at the free end of the wire and attach a long nylon string.
When you want to work 80m, draw the wire
Vic,
For those bands, I would recommend that you use a higher frequency
adaptation of the DXPeditioner's Battle Creek Special antenna (see ON4UN's
Low Band DXing). Add a 30 meter trap in the vertical section and put a 40
meter trap at the top, then use a wire from the top of the 40 meter trap to
