Four Square Layout
The array antenna elements should be arranged in a square, use
Table 2
for guidance in choosing
the best combination of frequency coverage and side length dimensions.
The diagonal corners of the square should point in the most desirable receiving directions.
Element 1 is the default forward element, Element 3 is the rear or null element.
Performance of the
RFS-2
can noticeably decrease if structures radiating even small
amounts of noise or signals are within 1-wavelength of the array
Measure side-to-side and then corner-to-corner to ensure the element locations are square.
Normally the
RFS-2
phasing unit is installed near the center of the four array elements,
above any standing water, with the connector side facing down. The placement of the
RFS-2
unit is not critical, however, the feedlines to each of the active elements must be equal in
length.
If you mount the
RFS-2
on a wood post, it should be grounded to a separate ground rod.
