Topband: 160m vertical saltwater grounding

[GEORGE WALLNER]

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.)
73,
George,
