Michael:
I have a similar 2nd floor shack situation (see QRZ page K5AMH).
It's very possible to put a few feet or more of ladder line inside the
shack and loop it to save space. An antenna analyzer should show
you about how much feed line to add to solve the problem.
What kind of antenna tuner or balun arrangement are you using?
I have a highly modified Johnson KW MatchBox which is entirely
floating from the ground (case) internally. This assures virtually
perfect feed line current balance, i.e. no common mode currents.
BTW, I have an interest in astronomy also and have a very nice
vintage QSL collection here; every hear of Southern Rhodesia?

Hi all,
Thanks Josh, Rick, and Gary for the suggestions. It never occurred to
me to try to adjust the length of my ladder line.
I can't do too much here....my antenna mast is affixed to my house and
my shack is on the second floor. The ladder line comes off the
feedpoint and makes a nice arc into my second story window. If I have
the feedline too long it will sit on a part of a roof overhang that
goes over part of the first floor.
Still, if I can just lengthen it enough to get a match on 40 meters,
I'll be happy. Looks like experimenting time!
