  Buongiorno, Mauro! Alexander R7NT make a semi-LOOP for LF 136 kHz several
  years ago using Al-Plastick pipes for the water 15mm diametre.

    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 =3D 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.

    73 de Mauro IK1WVQ
