I had the same experience with this antenna. In your wooden
ship this is just the ticket. I bought mine from Tim at Wings and
Wheels. Works great and is super easy to install.

There are a number of people in this group who used dipole
antennas.
I've got the L2 model from Advanced Aircraft Electronics in my
ASW-19,
it was $99 if I remember right.

Because I have a fiberglass tail boom, all I had to do was glue
the
dipole to the supplied strip of balsa, then glue the dipole into
the
tail boom in a vertical position. No need for a ground plane at
all,
and as you point out it radiates both upwards and downwards.

It seems to work very well, but I couldn't tell you just how
much
better it performs than a monopole under the same
circumstances. For
me its biggest advantage was the ease of installation.

Has anyone used a Dipole antenna on their transponder? I
understand that
the dipole gives better coverage above where the
"standard" antennas
usually only project down and to the sides. Aircraft Spruce
carries
dipoles, they are a little spendy, but might be worth it. Any
experience
out there?
