[CQ-Contest] 40 Meters Antennes - Yaguis - Verticals - rigid dipole...solutions pse.]

Hi Stan !

thanks you for your quickly answer.-

good questions, I think....

Well, the principal direction would USA and EU, In this way I have ocean
only, not montains in this 2 ways. possibly the salt water it's separate
of the antenna arround 10 meters possibly less if I want it..... if it's
better that the matils touch it the salt water, not problems.

This plan not it's for an antenna fixed, it's for contest or dx'p. I think
then that the maximum height would be 10 or 11 meters of some mastils, not
more...

TNX Stan !
