[Antennas] Ham stick dipole

[Frederick]

Hi
     When I tuned the ham stick it was on a metal railing and I now moved it 
to a wooden mast. Oddly this didn't seem to change the resonance much. I do 
think I might return to the single ham stick though. After all who can argue 
with the higher field strength. Even if it doesn't make sense.

God bless,
Mark
God loves you!
