Well, I don't believe in grounding except for safety reasons, because a good
rf to earth connection is so difficult to obtain ;-)
My believe is that if I am pushing some electrons into the wire, I have to
take them from somewhere else (my rig can't create or destroy them), and if
ELEVATED RADIALS: I think Joe hits it on the head here. A vertical with
elevated radials is essentially an OCF dipole. There is no particular reason
for the radials to be a quarter wavelength. They should be whatever length
lets you resonate the antenna with a feed impedance you can live
Further to that, if you desire, as I might, to have more radiation in one
direction, eg from here to North America, I would have one elevated radial
pointing that way and the radiation pattern tilts that way a little.
One further point not brought out so far: the antenna itself does not have

A vertical dipole can be balanced with the lower element shorter. It will have
more capacitance to ground, which makes it electrically longer. This is like
putting a capacitance hat on the end of an element.

Thanks for all the answers. I have a lot to read through, but I think I

The cleanest installation is to put the radials in the ground - but, not
portable at all. The idea is a capacitance connection with the earth. I
have used welded steel cattle fence in the past - I build a mat that is
about 30 or 40 feet out from the base of the antenna.
For raised radials -
Personally, I do wonder about the new fangled no radials required
antennas. But, I have an old R5 and it works well.
The no radials antennas are basically a vertical OCF - the short
decoupling radials are the short leg and the vertical is adjusted
through the use of traps, stubs and/or
Hi Joel,
You've asked why are elevated radials so important. If a vertical is
elevated above ground (perhaps on a post or on a roof) elevated radials are
a necessity because in order to use ground mounted radials you would have to
run a long length of wire down to the ground mounted radial field.
Hi Joel,
The ground beneath the antenna can have two effects:
1. It can become a part of the antenna's equivalent electrical circuit.
2. It has an effect on the antenna's far field due to reflection of the
antenna's field
By burying the radials and mounting the antenna on the ground, you
based radials. And you are going
to miss out on gain at the much lower angles.
I hope this helps.

Hi Joel
As you mentioned ... physical, portable, and safety issues aside the
difference between raised and buried radials is the difference in how
they perform their function; that is how
that applies here, Hi!

The SteppIR information is overly simplified. For the best current analysis
of elevated vs. on ground radials see the extensive data from N6LF -

Joe, the article I referenced clearly said to use 1/4 wavelength radials
when they are elevated. That's agrees with everything I've read and done
over years as well.
