G3XAP wrote a number of articles in RadCom (RSGB magazine) about this 
question.

December 1973 p 842 "160m dx from suburban sites"


November 1977 p 858 "The G3XAP directional antenna from the 
lower                               frequencies"

Ashton's conclusion was there is enhanced radiation in the direction 
of the top loading wire. His antenna used a 40-60' vertical element 
and a 130' top loading wire. To get omni-directional performance, he 
added more top loading wires.
