Jorge:
I have several 4-squares in the woods and most of them are on very sloping
ground.
I posted my results here a couple years ago. A quick search will find my
results.
Instead of following the slope of the ground, which is quite steep, I tried
to keep all the verticals
(all with raised radials) of the array in a plane as close to (as much as
possible) horizontal with the average
flatness of Mother Earth.
Phrased another way, on my sloped ground in the woods, the verticals closest
to my flat wide open field have their bases a couple feet above the ground,
but "down in" the woods where the land slopes steeply down, the bases of the
verticals are up 7 or 8 feet above the ground. They are "nearly" in a
horizontal plane with Mother Earth, but not quite.
They are pretty much all wire verticals, hung from trees with 2 raised
radials each.
With my rudimentary measurements I don't notice any huge discrepancy's in
any of the arrays, in any of 4-directions, except on 80m to the NW, where I
have metal and buildings in the way. I use the Comtek matching.
A convoluted answer, I know, hi hi
A shorter answer might be "I don't think it'll matter and even if it did, I
doubt you could measure it"
( I certainly would NOT level the ground, but that's just me)

hello
I want to build a 4SQ system, with four aluminium vertical antennas
My terrain is not flat, so I will do some work to level the ground
My question: is just enough to level the terrain where the 4 antennas will
be placed or is also necessary to level all the field included the field
occupied by the radials?
Would be very good to level ALL the terrain that will be occupied by the
radials and antennas, but if it's enough to level just the place of the
antennas, will save a lot of money
thanks!
