The template shows an imaginary circle around an antenna.
The spokes on the template represent imaginary straight lines
measured from the center of the circle to 36 points spaced
equally around the circle. Each straight line is 25 feet in length.
The numbers on the template (1–5) are a guide to show you
where to mark the field strength level the meter displays as you
measure.
Hint: To help measure a circular path around the antenna, tie
a slip knot in a 25-foot piece of rope or strong cord, slide the
knot loosely around your antenna, then use the rope as a guide
as you walk around the antenna.
Follow these steps to prepare the antenna site.
1. Starting at the antenna, use a compass to find due north.
Then walk due north and stop about 15 to 25 feet away
from the antenna.
2. Use an object such as a rock or a weighted piece of paper
to mark where you are standing.
3. Walk around the antenna in a circle, using more objects to
mark 35 more evenly spaced marks on the path.
Hint: You can quickly find the space to leave between each
mark by using a calculator. Measure the diameter of the
marked circle (from one side of the circle to the other). Then,
divide the diameter by 11.46.
