Four Square Array Manual and User's Guide
Array Solutions Four Square Array Pattern Steering System
Congratulations!
You have selected one of the finest phased array steering systems made. We have under-rated
the power capability of this system to assure the user high reliability under heavy use such as in a
48 hour radio contest. Please contact us if you have any questions about the product.
The Array Solutions Four Square Array system has two components: a relay box that will be
mounted midway between the four verticals and a control box that is connected with a 5-wire
control cable inside the operating room. With this system you will be able to beam in 4 directions
and also take advantage of the OMNI mode for domestic use to listen in all directions at once.
The system is available in standard quadrature feed and an optimized feed version and you can
purchase the optimization kit at any time to add to your controller.
Wiring the system:
A 5 wire connector is supplied with the controller switch. Table 1 shows the 5 wires to the
corresponding 5 wire terminals in the relay box and the control switch connector. You may use
our DC power supplies which are regulated linear supplies, or use one of your choice. A 2.1mm
DC coaxial connector pigtail is included for connecting to your DC supply. We recommend a 1000
mA or more power supply current rating.
You will need a cable with 5 conductors. Small gauge wires are fine and will fit inside the boxes
better than large rotor cable. For runs of less than 500 feet (152.40 m), #18 (1.02 mm Ø or 0.82

    The AS-4Square is pretty much plug and play and special instruments should not be necessary to set it up and get it operational in the normal quadrature feed situation. www.arraysolutions.com info@arraysolutions.com Four Square Manual, ver. 2.1 2611 N.

  • Page 5 Four Square controller. By using the “Two shunt compensation design system” by W1MK, you can predict the values necessary to optimize your array. For instance an 80 m four square would use about 300 pF of capacitance and 6 µH of shunt inductance.

  • Page 7 The system consists of four verticals in a square with sides 1/4 Wavelength long. The Array Solutions controller will power all 4 of these verticals in such a way as to accomplish a quadrature feed to each antenna, with the proper current magnitudes. The “rear” element in our diagram above is the one on the closest to us on the axis.
