Rob,
This is a good reference. Only one comment: I found recently on C6AGU that
on 160 m the 2 -3 foot tidal change cause only a small change in the SWR of
a tuned inverted L with its metal base standing in salt-water. I tuned the
antenna to resonance with an SWR of 1.2 at mid-tide. Between low and high
tides the SWR remained below 1.6. (Including losses in 300' of LMR-400
coax.)
