Section 1.4: 80m Base Coil Wiring (skip if 80m coil is not purchased)
(skip if you have pre-wired cable)
The 80m base loading coil is wired to a separate piece of 4 conductor control cable, we recommend
labeling both ends to distinguish it from the EHU control cable. A piece of tape is often an easy way to do this.
1. Strip approximately 2 inches of jacketing off of the end of the 4 conductor control cable closest to the coil,
being careful not to damage the insulation of the inner 22awg wires (figure 1.41). Trim off the foil shield,
support thread, and shield wire.
2. Strip 0.25 inches of insulation off of the 22awg wires, and place heat shrink over the wires (figure 1.42).
3. Using the provided ring terminals (PN 20-6043-01), crimp and solder them to the ends of the control cable
(figure 1.43).
4. You may now use the provided heat shrink (PN 60-1025-125) to weatherproof these connection points
(figure 1.44).
5. A small piece of coax seal should be used to seal the outer insulation of the 4 conductor control cable as
well (figure 1.45).
