16.1 Mounting arrangements
The MetPak unit is supplied with all the necessary fixings to attach to a mounting pole.
Instructions and tips about mounting are all contained in the manuals supplied on the enclosed
Gill Instruments CD.
Pay particular attention to the following:
Positioning
1. Mount at the top of and away from the mounting pole (i.e. ensure the head is clear of
and not beside the pole)
2. Clear of close obstructions likely to influence the readings (e.g. trees, buildings (wind)
and air-conditioning fans (wind and temperature & RH)
3. So as not to cause an obstruction to aircraft movements
4. Ensure that the head is correctly aligned to North (there are diagrams in the Gill
Instruments manual which identify this)
Electrical
1. Ensure that the mast and MetPak are earthed with suitably sized grounding cable (the
MetPak has an earth bonding point on the mounting arm)
2. The signal cable is properly and securely connected
3. The shield wire of the signal cable is connected to the Grounding point in the connector
box (see photo later)
4. The signal cable is securely supported in conduit, trunking and fixed with tape, clips or
wrap-ties at short centres

The MetPak is supplied with 30m of 3 pair screened (Belden type 9503 or similar) data cable
