e. Placement of Antenna Stakes.
(1) General. The antenna stakes are assembled by using three ground rods
without the grounding cable and clamps. (See illustration on page 2-19 and oppo-
site page.) To lay out the positions of the four antenna stakes, letters A, B, C,
and D are assigned for illustration purposes only. The letters are not markings on
equipment. Use the 100-foot tape measure to make measurements cited below.
(2) Antenna Stake A.
(a) Connect the tape measure between guy stakes A and B. Measure and make
a mark on the ground 13 feet (3.965 meters) from guy stake A. Connect the tape
measure from the mast base through the 13-foot mark and measure 60 feet (18.3
meters) from the mast base. Mark the spot.
CAUTION
Before hammering in the ground rod, make sure that the driving stud,
which connects to the ground rod via the coupler, bottoms firmly
on the ground rod.
(b) Attach the coupler to the ground rod; attach the driving stud to the
coupler, making sure the driving stud bottoms firmly on the ground rod.
(c) Put on protective goggles and hammer the ground rod into the ground
approximately 15 away from the vertical and the mast base, until about 5 inches of
the ground rod and coupler are above ground.
(d) Remove the driving stud. Connect a second ground rod to the first
with the coupler; and a third ground rod to the second with a coupler. Place a
coupler and the driving stud on top of the third ground rod.
(3) Antenna Stake B.
(a) Connect the tape measure between guy stakes B and C. Measure and make
a mark on the ground 13 feet from guy stake C. Connect the tape measure from the
mast base through the 13-foot mark and measure 60 feet from the mast base. Mark the
s pot l
(b) Repeat steps (2)(b), (c), and (d) above.
(4) Antenna Stake C.
(a) Measure 60 feet from the mast base in a direction opposite the direc-
tion of antenna stake A. Mark the spot.
(b) Repeat steps (2)(b), (c), and (d) above.
(5) Antenna Stake D.
(a) Measure 60 feet from the mast base in a direction opposite the direc-
tion of antenna stake B. Mark the spot.
(b) Repeat steps (2)(b), (c), and (d) above.
