Dont overlook perhaps an antenna you already have up,  I use an 80 meter 
dipole thats
fed with open line,  I short the open line at the shack and feed that 
into the receiver,
I have copied the east coast many times from Hawaii,  and of course all 
the other guys
between,   up to Alaska,  thats on 475KHZ.  Both CW and WSPR.  No preamp 
used.

So if your wanting to just listen and get an idea of whats there, maybe 
check your present
set up,   coax fed dipole would work the same if you short the coax at 
the shack end.
