Not necessarily true.  Strictly speaking, a half wave dipole is a 
ballanced antenna.  Although somewhat a different design than the 
original g5rv, those you buy today use the ballanced line as a sort of 
tuning stub, and most state you should run at least 50 feet of 50 ohm 
coax to the radio.  I ran one like that for years and it worked great. 
I also once ran a double sized one that worked fine on 160  Antenna 
lengths were doubled as well as the tuning stub.
