Hi to all,

saturday i have tested the our contest station in Mantova city in LF, and qso with G in aural CW seems not a problem with a 80 meters long vertical wire, slooping from the top of the tower, with 150 watts.

But wich may be the best sistem on this tower for LF, is possible to feed directly it, may be at the top?

The tower is exatly 80 meters long, with a base of 8x8 meters, and at 70 meters is 1x1 meters, and at 80 meters is 0.5x0.5 meters, so big antenna with big capacitance to ground, i think is a smaller version of Decca insulated tower, but this one is grounded.

Any idea??
