INSTALLATION PROCEDURE

DANGER
You can be seriously injured or killed if the antenna comes into contact with electric power lines. Verify that there are none nearby before performing the following procedure.

1. Select a flat and secure site to install the antenna base plate.

2. Place the base plate so the outside holes are positioned over the brick surfaces. Do not drill into the mortar between the bricks.

3. Using a carpenter’s level, plumb the antenna mast in at least two different locations on the side of the mast, as shown in diagram at right. These two measurements should be at right angles to each other. If the mast is plumb (aligned vertically with the bubble level), go to step 5. Otherwise, loosen the adjustment nuts.

4. Rotate the mast until it is plumb with the level, then use the torque wrench to tighten the adjustment nuts to 15 ft-lbs. If you are still unable to align the mast with the level, try using wooden shims. If they do not correct the problem, you will need to find another site to install the antenna.
