Installing the Head Electronics unit into an antenna

The following describes how the Head Electronics unit is installed into an antenna.

However, the same procedure is followed for installing the Head Electronics unit into the

1 GHz and 2 GHz belt box.

These first steps describe the installation of the Head Electronics unit into the antenna.

Generally it will not be necessary to follow these steps, as the radar head will already be

installed in the antenna.

1. Remove the cover plate from the antenna and store it safely in the carry bag.

2. Attach the lanyard (antenna only) to the back plate of the Head Electronics unit. This

is a push and twist fit.

3. Carefully attach the three gold plated connectors in the following order. Care should

be taken to ensure these connectors screw up smoothly. They should never be forced

or over tightened and under no circumstances should a non-torque spanner be used.

Care should be taken to avoid twisting these cables and connecting them in the

following sequence should ensure this does not occur. The numbered and coloured

sleeves should be used to identify the connectors.
