Hello Giulio,

About two years ago I had the same problems in a Dutch windmill. The wings
have a metal core and must be connected to a (very good) earth as long as
the windmill is not in use.
I tried the solution for an earthed mast described in ON7YD's website:
<> So I connected a wire to the top of the mill, went down with the wire to my
coil and went up again and from the top sloping at 45 degrees to a lamppost
25 meters from the mill.

Although the top of the windmill was (only) 32 meters high I had a very good
weekend working all over Europe.

73 es good luck.

ps. my TS850s RX is in repair but it might be nice to have a scheduled qso
if I am QRV again.

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??
The picture is at this site
73 to all de Giulio IK2DED.
