2. Calculate the expected signal loss for the following: 
  • Dropcable = 65 meters
  • Frequency loss = 1.9 dB per 10 meters

Explanation

Dropcable = 65/10=6.5
6.5 multiplyed by frequency loss 1.9 = 12.35

Submit
3. Calculate the expected signal loss for the following: 
  • Dropcable = 150 meters
  • Frequency loss = 1.2 dB per 10 meters

Explanation

Dropcable = 150/10=15
15 multiplyed by frequency loss 1.2 = 18

Submit
4. Calculate the expected signal loss for the following: 
  • Dropcable = 217 meters
  • Frequency loss = 1.8 dB per 10 meters

Explanation

Dropcable = 217/10=21.7
21.7 multiplyed by frequency loss 1.8 = 39.06

Submit
5. Calculate the expected signal loss for the following: 
  • Dropcable = 165 meters
  • Frequency loss = 1.6 dB per 10 meters
 

Explanation

Dropcable = 165/10=16.5
16.5 multiplyed by frequency loss 1.6 = 26.4

Submit
6. Calculate the expected signal level at the ETB using the following information.
  • Signal level at tapbank output = 28dBmv
  • Dropcable length = 180 meters
  • Frequencey loss = 1.9dB per 10meters

Explanation

Dropcable = 180/10= 18
18 multiplyed by frequency loss 1.9 = 34.2
Tap output = 28
28 minus 34.2 = -6.2

Submit
7. Calculate the expected signal level at the ETB using the following information.
  • Signal level at tapbank output = 19dBmv
  • Dropcable length = 138 meters
  • Frequencey loss = 1.5dB per 10meters

Explanation

Dropcable = 138/10= 13.8
13.8 multiplyed by frequency loss 1.5 = 20.7
Tap output = 19
19 minus 20.7= -1.7

Submit
8. Calculate the expected signal level at the ETB using the following information.
  • Signal level at tapbank output = 17dBmv
  • Dropcable length = 60 meters
  • Frequencey loss = 1.3dB per 10meters

Explanation

Dropcable = 60/10=6
6 multiplyed by frequency loss 1.3 = 7.8
Tap output = 17
17 minus 7.8 = 9.2

Submit
9. Calculate the expected signal level at the ETB using the following information.
  • Signal level at tapbank output = 25dBmv
  • Dropcable length = 126 meters
  • Frequencey loss = 1.7dB per 10meters

Explanation

Submit
10. Calculate the expected signal level at the ETB using the following information.
  • Signal level at tapbank output = 28dBmv
  • Dropcable length = 217 meters
  • Frequencey loss = 1.5dB per 10meters

Explanation

Dropcable = 217/10=21.7
21.7 multiplyed by frequency loss 1.5 =32.55
Tap output = 28
28 minus 32.55= -4.55
