[TowerTalk] Power ground

[on4kj]

  Hi Tom and all,

  I build my house about 20 years ago.
  Electricians did not use ground rods.
  The outside ground (or rod replacement ) is only a large burried loop of
wire, both ends connected together serve as a classic ground connection.
  The whole system has been agreed by the control institution.
