And the only thing achieved by the sloping termination is avoiding the 
necessity of using a separate guy wire to hold up the pole where the wire is 
terminated.  You have the same vertical antenna component whether the wire 
is sloped down gradually over a 15-20m. length or whether it is terminated 
immediately with a vertical wire.
