Example 2 Calculating the Total Feeder Attenuation
6.6 Calculating the Feeder Delay
This section describes how to calculate the total delay in the feeder system.
1. Use the feeder length measured in Section 6.3.3 Measuring Feeder Length
on page 82.
2. Find the delay value (ns/m) for the cable type in Table 15 on page 85.
Calculate the total attenuation for each feeder and jumper, by multiplying
the length in metres with the delay per metre.
3. Add the delay for the feeder and the jumpers.
4. Enter the result of the calculation in the test record.
5. Calculate the feeder delay for all antenna feeders.
