Topband: Alpha Delta sloper (DX B)

[Herb Schoenbohm]

Ed,  Everything depends on the size and type of tower supporting the 
wire plus of course the ground system you have in place.  Some reports 
are that the support structure, if it is metal, is merely excited with 
RF and with the feed wire and the tower does much of  the radiating.  
There has been a wide range of reports of failures and successes i have 
read over the years.  Maybe some modeling of this design from a wooden 
pole or tree vs. a steel tower with a beam on top would be nice to see. 
IMHO a shunt fed tower with a cage feed and top loaded with some beam(s) 
is the way to go.
