3-4 Amplifier Setup
Substituting this information into the above equation provides the following result:
11 dB + 26.0 dB − 12 dBmV − 14 dB = 11.0 dB
The slope of the required equalizer is 11 dB. Table 3-1 and the graph in Figure 3-1 show that
11 dB of slope is caused by approximately 14 dB of cable at 1003 MHz. Therefore, the correct
equalizer is model SFE-100-14.
When selecting an equalizer, choose the next lower value if the exact value is not available or in
cases where the calculated value makes two choices possible.
Table 3-1 helps you choose the correct equalizers and also lists insertion loss at various
frequencies.
