Topband: 160 meter L

[w8uvz at voyager.net]

Tree and Rick

Pretty much the same way a "Battle Creek Special" vertical is configured. 
Vertical tubing portion to 80 m trap and in the BCS, a 40m trap along the 
way.  From top of 80 m trap, a horizontal wire which completes the 160  m 
(Inv L) section.  And Tree is correct in pointing out the need for a trap 
for 80 m that will handle the hi current and voltages, as we've learned 
along the way of 30 years in building and loaning these BCS units.

At least on ham that I know of who has done this is Wayne Mills, N7NG at
his home station in Wyoming.  Seems to work very well on both 80 and 160
meters.

Don't skimp on the components used for the trap however.  Lots of high
voltages and currents involved.
