In addition to the suggestions provided by others you might think of 
using a full wave loop antenna. It's size is a bit unwieldy for indoor 
use however you can create a two or three turn loop that shrinks the 
antenna to quite a managable size. It also provides the most gain you 
can get in a single wire antenna. The calculator at this page:

Will give you the dimensions. You can feed it direct to your receivers 
with either 50 or 75 ohm coax and if you mount the antenna on a frame 
you will be able to rotate the antenna to maximize your signal. The edge 
of the antenna is a notch in the pattern so you can also rotate the 
antenna to minimize interference.

Despite what others have said here, a good mast mounted LNA type 
amplifier connected right at the feed point of the loop will improve 
your weak signal performance however it is susceptible to overload from 
nearby strong signals. I am talking about the kind of amp that is 
designed to be mounted at the feedpoint of a yagi antenna not the kind 
designed for use as a signal booster on long coax runs. The Channel 
Master #3041DSB Deluxe Antenna Amplifier is a good example.
