Antenna Siting. Wherever possible, the antenna should be located near good roads to
minimize difficulties in supplying the site. Try to avoid underpasses, power lines, or
power units as they may cause weak or distorted signals. Better results normally will be
obtained when the antennas are high and clear of hills, buildings, or other obstructions.
The antenna site must be reasonably flat, with a central clear area of approximately 10
square feet. Figure 17 shows the antenna site. The separation between the mast
assembly location and the shelter, containing the AN/GRC-103, should not exceed 25
feet. There must be clear aerial paths to the guy stake locations. The three guy stakes are
equally spaced on a 30-foot circle which is centered in the central clear area. The slope
of the clear area should not be more than 15 degrees.
