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
