What I really want to know is whether the ATS-909 will work ok with a
long(ish) wire outside feeding a 50 ohm coax via a 9:1 transformer, or if
that would cause more bother than connecting a wire directly to it and
putting up with local noise picked up from nearby buildings.

lets go back to the beginning... this is what i would do.
1. hook up whatever coax you have to the radio and run it as far
outside away from the house as it will go.
2. hook up a wire directly to it as long as you can go in whatever
random direction you may be able to go
3. enjoy.

if in the future there are signals that just aren't strong enough, but
still above the local noise, then start playing around with either a
matching network or a preamp. *but until you know how well the
receiver by itself works with the plain wire/coax you are wasting time
over designing something you probably won't need.

You may find that a good RF ground more benificial than any particular
antenna. I discovered this while in the military and had a chance to
hook my little cheap portable Setico rx to an antenna made of 20ft of
emt conduit and the ground system on an abandoned comm unit. Lots of
good info arounf on RF grounds on the web and this group.
