* The principal operating position of the antenna selector is with the cover
up (connectors pointing down), but when it is indoor used any position is
OK.
2-3. Connections
Connections must be accomplished in the order described below, before
you apply power supply or control to the antenna switch.
a) First tighten the lightning protection grounding leads under either of the
two wing nuts of the antenna switch.
b) Preparation of input control cable.
A 6-wire shielded cable should be used for the input control. The needed
wire cross-section depends on the distance from the antenna switch to the
control unit (for instance ACOM2000S automatic antenna selector) in your
station. You can determine cable specifications proportionally from the fol-
lowing table:
Cable lenght,
meters (feet)
maximum
wire cross-section,
mm² (AWG, SWG)
6x, minimum
wire diameter,
mm (inch/1000)
6x, minimum

Before trimming and soldering the first cable end, thread all connector ac-
cessories on the cable end in the following order:
- the hollow nut (oriented with the smaller diameter to the cable end),
- the first of the two washers,
- the plastic ring,
- the second washer.
