The original elevated radial layout used was very simple. It's a sort of "tic-tac-toe" topology with the 4 verticals at the intersections as shown below. The 8 corner radials were 34' in length; approximately a quarter wave.

40m Ground Mounted Four-Square Conversion from an elevated radial design to a conventional in-ground mount. The 40m 4-square was the first antenna built when I moved to this site.

As the name implies a 4-square is a square with an antenna element at each corner. In the majority of cases they are verticals such as ground planes or vertical dipoles.

Apr 11, 2022 · Bei 4-square-Antennen sind elevated radials sehr beliebt, insbesondere im Portabel- und DX-Stationsbetrieb weil dort der Aufbauaufwand entsprechend geringer ausfällt. Unser Funkfreund Franz, DF6QV, beschreibt in seiner Ausarbeitung nicht nur hervorragend die Theorie, sondern gibt auch gute Vorschläge zum Aufbau und der Einspeisung der Elemente.

This article shows how to modify a conventional four-square to provide eight directions of fire instead of the normal four. The extra directions are lo-cated at points which are mid-way be-tween the existing four, yielding a total of eight selectable beam-headings spaced 45° apart.

The "standard" elevated radial scheme has four or more radials elevated above ground by 4' to 10' with the base of the vertical also elevated so that the radial fan or screen is essentially flat.

Let’s say that an elevated 4-square has 4 vertical elements (each with 4 elevated radials) in the following configuration: N O R T H L1 L2 L L E E D D G G E E L4 L3 S O U T H Normally one would assume that the radials are reasonably horizontal.

I used 100 radials on each antenna elevated 20 feet on a 80 mtr 4 SQ and the antenna was a pure killer. That antenna did crach and after rebuild it became 40 radials per ant elevated 10 feet, I will increase number of radials this summer.

The Hi-Z Antennas 4-square receiving system utilizing shortened vertical elements has been designed to provide a relatively small footprint high-performance receiving antenna for the Amateur low bands covering 160 through 40 meters.

The DX Engineering Transmit Four Square system consists of a Transmit Four Square Control Console that has four momentary contact light-touch push-button switches for direction control and one push-button for omni selection.
