Tables 2 through 6 list the power consumed and dissipated by the ELU-319 List 5E and List 6E when it is used
with any of the four basic doubler types in the HiGain family. The maximum current drawn by the CO supply is
also listed.
Table 8
covers single doubler, line-powered circuits on 9 kft, 26 AWG (0.4 mm) loops.
Table 9
applies to two doubler, line-powered circuits on 9 kft, 26 AWG (0.4 mm) loops.
Table 10
applies to three doubler, line-powered circuits on 9 kft, 26 AWG (0.4 mm) loops.
