The 4 verticals shown in the picture, is that a phased array?

Looks like an 80m Four-Square array to me. Wish I had the room for one.

i run a 208ft dipole for 75 and 80 mtrs,no tuner...no swr at 25 ft...works great...73s de n09zna/JW

There is more to this than meets the eye. A 208 ft. dipole, in a standard dipole config. would not present that good of an SWR especially at 25 feet. It must be an OCF dipole is it?

As for the 80m four-square array, anbody ever work ZS6CCY on 75m? He has one and it works FB! He even managed to pull my little 100 watts into a crappy inverted L with no radials out of the ether a full two hours after his local sunrise hence my saying I wish I had the room for one. Well I do actually have the room but not without at least two of the elements being on the front lawn.

what would the foot print of the 80 meter array be?

A standard 4-square array for 80m would consist of four full sized 1/4 wave verticals each about 63 feet high and laid out in a square that is about 80 feet on a side. That allows any two active elements to be spaced about 120 feet apart or 1/2 wavelength. The antenna has four distinct beam headings aligned with the corners of the array. Here is the one at ZS6CCY in Vaalwater South Africa.

Here is Bill at the base of one of the verticals.

Awesome.

Not possible. Even if it were theoretically perfect, the SWR would be 1:1.

No SWR = No forward power.

No SWR = No forward power.

No pollution from coal no AC supply.

I'm assuming by no swr you mean the vswr reading is 1:1, which would suggest you have very lossy coax.

at approx .1 wavelength off the ground all your dipole is doing is cloudwarming.

The photo is of G4AMNs 80m Foursquare using Antenna Engineering's full size 80m elements. The array has 120 radials on each element and 80 radials at the centre, uses a modified 0 110 220 deg phasing network.
