Seawater Grounding for High-Frequency Radios


Seawater Grounding for High-Frequency Radios

I may have posted this, or possibly someone else did, but in case it was not...

This is a good article by Gordon West on using Sea Water as your RF Ground vice running 100 SQFT of copper. Mr. West makes some very compelling arguments against using copper. This is an argument that may never end regarding Copper RF Ground vs Sea Water Ground.

(Download it and put it with your other documents)

Enjoy! ... onWest.pdf

A good article indeed! Gordon does have a way of cutting through the BS.. :)

We use a 1 square foot plate of copper and find it works quite well, both ground wave and sky wave, and even after it became fairly well encrusted with growth it worked well. All of our thru-hulls & exterior metal is bonded, and connected to the radio ground via the negative power lead, we have not experienced any extra corrosion or zinc loss due to the copper radio plate.
