LF: questions about a tx square loop fpr 470KHz

[IK1WVQ Mauro <ik1wvq@stmb.it>]

73 to all,

I would like to know your opinion about this:

I can made a square TX loop for 470KHz of 7 * 3 meters (see picture) in
the terrace of the building where I live (6 floors).

the questions are:

- it is enough a 6mmq copper electric wire ??  (20W is the output
power of my tx).
- single turn or two turns spaced 10cm max ?? (two turns =  less pF
required to take the resonance).
- Is this a good idea to start to trasmit on 470KHz WSPR ??

thanks in advance for your attention.
