I used a cheap kite for LF tests as GW3XDV/P several years ago. The
first time was a success - 136kHz CW contact with SM. The next time -
an attempt to make the first (and only) GW-GI QSO on 73kHz - was a
failure because the wind was too low, even beside the sea and when I
relocated to a mountain top..
To reduce the weight, I used thin wire twisted round the strong kite
string. A problem was cause by high voltages close to the ground when
the kite dipped, so I would recommend using a small mast (8m of
fibreglass?) at the bottom end of the antenna wire.
