[600MRG] Approved 2X

[Dave Riley]

re: Approved 2X

Jeremy, you are one step away from the perfect RF counterpoise, a small 
ship...

Look at where most of the 600m long haul DX signals are to/from sea 
huggers...

No need for a lot of radials there... Maybe one radial is a great start 
compared to a 120 radial desert sand setup...

A remote transmitter beneath those overhead lines makes for a great 
above ground beverage 'helper'...

Let's hear how you did...   73s from DaveR aa1a

My thoughts for the ease of getting some bit of signal out, I will operate a 70 vertical, irrigation tubing on insulated ground mounted base. Guyed and incorporate a cap hat as the top guys.
> I am looking for some advice on my ground system. The earth at this location is eternally damp to wet at less than three feet deep. High salinity due to the Pacific. Conductivity is very high when poking around with a megger, even in just damp sand. Sometines just a few ohms over a dozen feet. Will I even require much effort in a raidial system or counterpoise? I am thinking environmental influence on tuning the antenna may be significantly less with a substantial ground plane versus just conductive earth?
