1
Loosen the strain-relief bolt and top bracket, slide the RF
and control cables from the interface unit into the bracket,
then tighten the bolt.
NOTE: The RF cable has heatshrink at the point at
which it sits in the strain-relief bracket.
1
Connect the RF and control cables to the respective
connectors at the mast-end of the tuner unit.
1
Seal the connectors using self-amalgamating tape.
1
Remove the bolts from the HV links at the dipole end of the
tuner unit.
1
Apply Alminox conductive grease to two lugs and one of
the bolts, then secure the lugs to the HV link using the bolt.
1
Repeat for the other lugs, bolt and HF link.
1
Identify the inner, centre and outer dipole elements (4 of
each type).

1
Apply Alminox conductive grease to the non-slotted, raw
metal sleeves that slide into other dipole elements.
1
Slide a loose compression clamp over each dipole element.
1
Slide each centre dipole element into an inner dipole
element and secure with the compression clamp from the
centre dipole element.
1
Slide each outer dipole element into a centre dipole element
and secure with the compression clamp from the outer
dipole element.
