The sort of classic 600 meter antenna is the Marconi-T.  It does require 
ground radials.  You can also use an Inv-L if you don't have room for 
the "T".  Either will have a very low radiation resistance at 630 meters 
for the heights average hams can get, and you'll need a series capacitor 
to tune out the reactance if you are going to transmit.

A better choice might be a magnetic loop, possibly with a preamp.
