Ok, here's the antenna Joe's talking about:

The MFJ-1622 Apartment Antenna covers 40 through 2 Meters, mounts outdoor to 
windows, balconies, railings, and works great indoors mounted to desks, 
tables, and bookshelves!
This Apartment Antenna lets you operate 40 through 10 Meters on HF and 6 and 
2 Meters on VHF with a single antenna! Its universal mount/clamp lets you 
easily attach it to window frames, balconies, and railings. It also works 
great indoors mounted to a desk, table, or bookshelf. Its not a five element 
yagi, but youll work your share of exciting DX!
The highly-efficient air wound bug catcher loading coil and telescoping 5 
1/2 foot radiator lets you really get out! The radiator collapses to 2 1/2 
feet for easy storage and carrying.
It includes coax RF choke balun, coax feed line, counterpoise wire and 
safety rope. The operating frequency is adjusted by moving the wander lead 
on the coil and adjusting the counterpoise for the best SWR.

So, it sounds like it might be a bit of a pain to tune.  I wonder if anyone 
can comment on those magnetic loop antennas?  I remember a discussion of 
them several months ago on this list, but can't remember any specifics.

Another possibility is an antenna in the attic.  Joe, does your apartment 
building have an attic, and could you possibly put an antenna up there?  I 
have an Alpha-delta 40 through 10 meter dipole in my attic, and it works 
pretty well, even on 40 meters.  It is 40 feet long, and just fits in my 
attic.
