Installing the High-Frequency Drain

This procedure describes how to install the High-Frequency Drain. The purpose of the High-Frequency Drain is to combat the effects of impedance on the ground wire. The High-Frequency Drain does this by dissipating the high-frequency transient voltage spikes through a short ground run with an inline 1 Ω resistor.

To install the High-Frequency Drain
  1. Find a structure to which the resistor heat sink can be secured. The following example shows the resistor heat sink secured to the attachment arm connector pipe (A).

  2. Trim a short section of the 12 AWG HFD wire to run from one end of the resistor to the rope guide (B). Connect it to the rope guide assembly using the supplied female disconnect terminal.

  3. Trim another section of the 12 AWG HFD wire to run from the other end of the resistor to unit case ground (C).
