Hardware Installation
1. Attach the Weatherproof RF Cables to the connectors
labeled Chain 0 and Chain 1 on the Rocket.
2. Attach the Rocket to the Rocket Mount.
a. Align the mounting tabs on the back of the Rocket with
the four mounting slots on the mount.
b. Slide the Rocket down until it locks into place.

3. Connect the other ends of the Weatherproof RF Cables to
the RF Connectors on the antenna.
4. Slide the Protective Shroud down over the Rocket until it
locks onto the Rocket Mount.
Note: If you have difficulty locking the shroud into
place, try adjusting the placement of the RF Cables.

5. Attach the U-Brackets to the antenna:
a. Secure the Slotted U-Bracket to the upper Mounting Lugs
of the antenna using two Serrated Flange Nuts.
b. Secure the other U-Bracket to the lower Mounting Lugs
of the antenna using two Serrated Flange Nuts.
Note: Orient both U-Brackets as shown below.

6. Insert two Carriage Bolts into each Pole Bracket.
7. Attach each Pole Bracket to each U-Bracket using two
Serrated Flange Bolts. Hand-tighten the bolts.

8. To mount the antenna to the pole, slide a Pole Clamp over
each pair of Carriage Bolts. Secure each Pole Clamp with
two Serrated FlangeNuts.
Note: The mounting assembly can accommodate a
Ø 40 mm - 80 mm pole.

9. The antenna has an electrical downtilt of 2°. To further
adjust the elevation angle:
a. Loosen the four Serrated Flange Bolts on the U-Brackets
and the two Serrated Flange Nuts on the upper
PoleClamp.
b. Slide the antenna to the desired tilt. (The brackets may
slide along the pole, depending on the angle of the
elevation tilt.)
c. Tighten all bolts and nuts to approximately 25N-m.
