The Mojo is in the sea water which has a conductivity of about 500 millimhos/per meter. The best of soils are about 30 millimhos/meter and average soil about 5 mmhos/meter. A small island is as near to a perfect ground plane as you will find. --- Björn Mohr [EMAIL PROTECTED] wrote: I agree!

For verticals there's a 2 or 3-fold effect: 1a vertical over sea water will have very much reduced losses in the near field, ie close to the antenna so increasing its efficiency, ie raising the 'power output' compared to a land situation 2the increased conductivity in the far field

I agree! Although the K3 is a great radio, 90% of the mojo is antennas and location. If you are really interested in the secret of vertical antennas near salt water check out this site; http://k2kw.com/k5k/dxcomp.htm 73 de Björn /SM0MDG On 080222 5:41 , Ron D'Eau Claire [EMAIL PROTECTED]
