Loading the top will make it resonant on 160m. You can also use a single
80' wire and run it on an angle toward the ground. There will be slight
directivity away from the wire. I used a similarly loaded homebrew 54'
freestanding vertical at P40A with good results over a poor ground system.
I am not sure how well this will work on higher frequencies if you are
looking for a multiband vertical.

I just bought a 33' 10-80m zero-five vertical and am waiting for it to
arrive. My reason to buy this antenna was first I like a vertical for
the
lower bands and I was hoping to use it on 80 & 160 with some mods. I do
not
want to leave this antenna up all year so I will take it down in the
spring
and put it back in the fall ( grandkids use the back yard in the summer)
and
I did not want a HUGE vertical
I called zero-five last Sunday to leave a msg and got a call back from
Tom a
few hours later (GREAT SERVICE already) and I asked about using this
antenna
on 160. He said add 80' of wire (40' to each side) at the top and make a
T-configuration and pull the wires as high as possible.
That is not a problem but is there anyone that has done this and what
was
your results. I plan on 30+ radials right now .
This will be a experiment most of the time and it'll be down in about
3-4
months until the fall..
Thanks
John
