It's been mentioned here before, but try a counterpoise wire connected to
the ground terminal of your rig, or of your external tuner if you are using
one.
The other end of the wire connects to nothing.
This is a cheap way of accomplishing what MFJ does with their artificial
ground tuner.
Make it a quarter wave on 40 meters, and it should cover you on most of the
other bands. If it doesn't then add a separate quarter wave wire for
whichever bands you wish.
You can run it around the baseboard, or toss it out the window and run it
along the ground parallel to your house.
Of course, don't let anybody get hold of it while you are transmitting.
When I lived in a second floor apartment, a counterpoise was often the
difference between an antenna that would tune and radiate vs one that would
not.
In the case of RF on the equipment, the counterpoise will, in many cases,
carry the rf away from the equipment, greatly improving your operating
conditions.
