If you are talking about the "end-fed zepp" the unterminated feeder, 
sometimes called the "dead" feeder somewhat balances out the "live" feeder 
that connects to the end of the antenna.  While the balance is not perfect 
and cancellation is not complete, the feedline radiation is significantly 
less than with a simple one-wire vertical feeder ( which would qualify the 
antenna as an "inverted-L").
