[TowerTalk] 30/40m on 1 boom

[Douglas Ruz / CO8DM]

You can use Open Sleeve method...It is the same describe by Herbert.

Feeding only the 40m driven element and with only one boom.

The 30m driven element is not open in the center like classic driven 
element...it is close like a director or reflector...just in one piece.

GL,

Doug, CO8DM
