I recently acquired a Hammarlund HQ-129-X, and I was wondering if anyone had
tips on effective antennas for someone living in a first floor apartment. I
do
NOT have the capability for ANY outside antennas...


Well, be aware that noise from yours and your neighbors' electrical
appliances/dimmer switches, etc., will be a factor, but you could try to run as
much wire (of any type, but insulated with a plastic which matches your
paint/wallpaper might be a nice touch) around the ceiling or floor of your
entire apartment.
Some kind of loop antenna(s) or preamplified active antenna may be an option as
well. If you absolutely cannot get any wire outside, then you have to be
creative. But if you at least have a single window, downspout, or other access
to the ground outside, you could run wire around as much of your apartment's
perimeter as possible, as hidden and 'dug-in' as possible, without getting
discovered or in the way of groundskeeping or your landlord. There are a LOT of
sites dealing with hidden, compromise or 'stealth' antennas, try a general
search for hidden or stealth antennas and see what youc an find.
Good luck-
