You are still the S3. Due to a shortage of supplies, you have no nonlinear graph paper.
You have to establish a radio system between points E and F. Using linear graph paper
(page 2-22), conduct a LOS profile based on the following:
Elevation at point E
300 feet
Elevation at point F
200 feet
Antenna heights at both sites
50 feet
Distance from point E to F
16 miles
Significant high and low points are:
2-mile distance
300 feet
4-mile distance
325 feet
6-mile distance
250 feet
8-mile distance
280 feet
10-mile distance
200 feet
12-mile distance
150 feet
14-mile distance
200 feet
Based on your initial profile, LOS exists between points E and F.
A.
True
B.
False
8.
Using the 8-mile distance as your reference point, determine after correction the height of
the obstacle at the 4-mile point. Use the conversion chart nomograph in Figure 2-7, page
2-11.
A.
About 317 feet
B.
About 400 feet
C.
About 300 feet
D.
None of the above
9.
Based on the corrected profile above, LOS exists between points E and F.
A.
True
B.
False
