Topband: 160m int L

[i4jmy at iol.it]

That antenna is basically an upside down GP with two radials, and it works fine if the radials are quite high above the ground, and if the vertical section is ¼ WL. 
Opposite to an inverted L the horizontal wires does not load the vertical section which must be ¼ wave long.
The other critical point of this antenna is the feed line, that should run away normal to the horizontal wires and not to couple with vertical section.
I used such kind of antenna some 20 years ago with good results. A practical approach is to slope some 45° the vertical section, like is done with a classical ¼ WL slooper system.
All considered, anyway, if having two or 3 poles able to hung so high from ground the horizontal sections, then some phased verticals (i.e. two wire T verticals ) are possible, and is preferable to deal with radials, comfortably, at ground level.
