Hello Marc,

> For the top capacity ,I'll use 4  X 13 meters wire (25-25-25-25)cm. at
>10meters hight.

A word of advice : from my experience with multiple topload wires you will
win relative little capacity with only 25cm spacing. I found a kind of
'optimum' at 80cm spacing, most others with paralllel topload wires have
0.5 - 1m spacing.
If possible space the wires at least 50cm. If for some reason you are
limited to 75cm space, then you will get about the same result with less
wire (= less weight) when you take 3 wires spaced at +/-40cm.

Good luck in your attempts to make your first QSO on 136kHz, I remember
getting pretty desperate when I started on this band. I was QRV late March
(1998) and it took until the end of May before I managed to work G3XDV
(what was probably the first 2-way QRS QSO ever).
