Figure 3. Typical MHU Clamp Mounting Kit Components
1. When installing on a pole a clamp kit ( Figure 3 ) is required. The kit is designed for tube
diameters of 30 to 140 mm.
2. Before going up to the mast, temporarily remove the connector protector plugs, inspect the
7/16 DIN connectors for damage, and return the connector protector plugs to their
respective connectors.
3. Install clamps on pole and route through the mounting openings near the center of the MHU.
4. Position MHU at the desired location and tighten clamps securely.
2.2.1 Installing the MHU Ground Cable
Good grounding of the ClearGain MHU is important to protect the unit against voltage surges.
These surges may be caused by lightning or inadvertent contact with high voltage power lines.
Install the ground cable as follows:
1. Connect the ground cable to MHU bottom using M8 star washer and nut.
2. Connect the other end of the cable to a good ground (site ground) with a reliable joint.
Note: All hardware is specified in metric units. The threads are sensitive to damage.
