The advice we were given from Hi-Z for a new 4 square was not more
elevation difference between elements than ~4 feet. ~20% of element
length. The topography that happens between elements, eg spanning a
creek, might not matter much given the simple single ground rod ground
per element, but

I have a pair of VE3DO loops spaced 5/8 wavelength that work just fine.
Both are on relatively flat ground, but with lots of slope all around.
Write-up is here.
Jim,
Thank you very much.
And I can confirm that even short (300') Beverages work on slopes.

I don't think a 4 square would work i these conditions.
I was surprised how well the short Beverages worked out.
Both I and NI6T, a great engineer and topband op, have

Elevated 160M radials really need

Yes, this both my experience and the advice I got from N6BT, who has
done LOTS of work with verticals. N6LF, who has also done lots of work
For a portable helix loaded 160m vertical, I measured 1 and 2 127ft
radials at 3.5ft and 6.5ft above ground (average or worse) and found a
significant difference in the resonance R.
1 radial 3.5ft 50 ohms
1 radial @ 6.5ft 33 ohms
2 radials @ 6.5ft 28 ohms
Which quantified the change in ground
My property is similar, sloping away from the house to maybe 40’ below in all
directions. I wonder how much of an issue that is with a 4 square. The property
is about 300 x 300 square so there is no real room for any beverages. The 4
square would be sitting maybe 25’ below the high point (SE
I resent this from my PC...
For some reason when I send email to this reflector it takes out all spacing in
my text.
Makes it hard to read...
Frank,
Thanks for help.

Frank,Thanks for help.The property is on a slope that dumps into a creek then

I was surprised how well the short Beverages worked out.But wanted to try to do
better. Last summer I was able to get up a 580' Beverage
After a few days of poor DX conditions, looks like 160m propagation is
getting back to normal . . . I myself managed an S9 report from Washington
State last night.
So hope we'll see lots of stations looking for CW contacts on the band
tomorrow evening/Thursday morning.

Rudy, N6LF, wrote a great article on his elevated radial experiments.

Rudy says,
"1) Use at least 10 to 12 radials.
2) Make an effort to have the radial system as symmetric as possible.
3) Keep the radial
Mike, All ¼ wave verticals have the same elevation angles. The question is
what is the feedpoint efficiency which is dominated by the ground. That
ground is a combination of your soil characteristics and the radial field
design. In my opinion, 2 elevated radials about 5 ft above the ground is
Hi Fred,
A single 300 foot Beverage has excellent front-to-back ratio but
very broad 150 degree 3 dB beamwidth on 160 meters,
A 580 foot Beverage has approximately 80 degree 3 dB beamwidth,
and it works very well on 160, 80 and 40 meters, one of the
reasons why that length is so popular.
While watching another one of Steve's(VE6WZ) awesome videos got me to
thinking about doing this to with short Beverages...
I thinking about end-fire phased where one stepped in front of the other.
I have read what ON4UN has written on this subject and just how close
you can have Beverages with
