Hello group,

While resting a little on The local beach in Numana , Italy, i've managed a good
Deal with a vendor and aquired a big kite to try some antenna tests.

Stephan, how's big a kite should be to
Fly a suitable Cooper / iron wire ?

That depends on the kite itselfe, the weight of the wire but in the first way it depends on the location! If you intend to fly the kite on flat land and/or on the coast where the wind is mostly stable and strong then a small kite, maybe 1 m^2 is OK. But if the wind is unstable and the velocity is low then you need more area. My "small" kite has 3.6m^2 and the big one has 8.1m^2. For example, the 300m vertical was hold stable at the sky for hours in my 10th VLF experiment. The small kite carries the wire when the wind speed is 18 km/h or say 3-4 BFT. The big kite just needs 10 km/h or about 2-3 BFT to carry the 300m wire.

The picture looks like this is a small kite, smaller than 1 m^2. But you need a thinner line for the kite and if you use a thin wire which is only 100m long or so and fly it on the coast then this should work!
Just try it. :-)
And don't forget to tell us :-)
