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.
