Imprimer la pageThe 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. It is powered with 1A of current at +90
degrees, the next two elements are crossways in the box are powered with 1A of current at 0
degrees in phase, and finally the element furthest away is powered with 1A of current at -90
degrees of lagging current. The direction of gain is through the diagonal of the box towards the
-90 degree lagging element. The array will have a forward gain of 5.5 dB over a single vertical.
Note the following diagrams are normalized to 5.5 dB of gain over a single same type
vertical. Do not confuse 5.5 dBi with real gain, which can be more with tall verticals and
good ground conditions. This is to display the gain over same type vertical ignore the dBi
notation and consider it as dB reference over single vertical.
