Question:

Is you are making a HF-ground (radials just below the surface) Should
these radials be insulated or not?

In one of my antenna books, by W6SAI, he recommended uninsulated wire
for buried radials.

To cut down on copper corrosion, I use enameled #14 magnet wire.

It makes no real noticeable difference in operation, however,
insulated wire will not deteriorate as fast in the ground.

Insulated will reduce corrosion. Don't bury them any deeper than
necessary. Lying on top of the ground is better. Dirt is not a good
antenna element.

Bill, I often see the assertion that it is better to not bury radials.

Can you point me to any reputable texts or experimental evidence that
shows the difference between shallow buried radials and radials lying
"on top of the ground"?

Corrosion is often cited as a reason to use insulated buried radials,
but is corrosion a significant risk in most locations. We widely use
buried copper water pipes here, and copper clad earthing electrodes
for the MEN power supply earthing, yet they don't seem to suffer
significant corrosion in most places.

It seems to me that insulated buried radials are likely to be less
effective in a lightning protection role.

I note that you decline to subtantiate the reasons underlying your

Has anyone references to sound evidence that supports Bill's advice
that radials "Lying on top of the ground is better." than buried.

Owen;

Given the expertise that Bill has accumulated over the years and the
good advise he has given to anyone who asks I think that your attitude
needs modification. When you were in school did you challenge your
teachers this way? I think not. If you diagreed you kept it to your self
or checked it out on your own.
For what it's worth everything that I have read tends towards placing
the radials on the open ground, usually staked down so as to prevent
tripping or getting caught in a lawn mower.

Note to Bill: I know you don't need anyone to defend you but this guy
isn't going to take any answer from anyone. I suggest that we drop him
as a thread. I just know his response is going to be at me demanding
positive confirmation. ;^)..

Hello sir, maybe YOU should nip in the yard with a shovel and some wire
(don't forget your strippers) and do some tests yourself! old man
