Coaxial Cable Connection to Mote
1.
Continue running the coax cables down the mast being careful to avoid any sharp metal parts
that could cut into the cable.
2.
Coil any excess coaxial cable neatly under the Mote enclosure and secure it with cable ties.
Ensure there is adequate cable to leave a drip loop.
3.
Remove the protective tape, check the connector for any dirt, and screw the right-hand
antenna—viewed from standing behind the Mote and looking towards the sea—into antenna
“A” connector.
4.
When tight, wrap the connector with PVC tape—see Figure 16.
Figure 16
5.
Insert remaining cable into port “B.”
6.
Wrap with PVC tape

Mote Grounding
Motes should be grounded to minimize damage due to lightning strikes. Current from a lightning
strike will flow from the lightning rod, down the mast and to ground via the ground wire and stake.
1.
Use a sledgehammer to insert the 4’ or 5’ earth stake. If the stake cannot be inserted because
of hard ground, lay the stake on the ground and cover with rocks if possible.
2.
Strip 1” of 3/8” wire and clamp it to the earth stake—see Figure 17.
Figure 17—Earth connection
3.
Run the earth wire up to the tripod and cut to length. Strip 1” and fit it to the tripod earth tab
using a flat blade screwdriver—see Figure 18.
