Frequency Selection (DFS) requirements.

Installation Requirements

• Rocket™M3/M3 GPS or RocketM365/M365 GPS

(soldseparately)

• 12 mm and 13 mm wrenches

• Shielded Category 5 (or above) cabling should be used for

all wired Ethernet connections and should be grounded

through the AC ground of the PoE.

We recommend that you protect your networks from the

Hardware Installation

1. Attach the RF Cables to the connectors labeled Chain 0 and

Chain 1 on the RocketM.

2. Attach the RocketM to the Rocket Mount Bracket.

a. Align the mounting tabs on the back of the RocketM

with the four mounting slots on the bracket.

b. Slide the RocketM down until it locks into place.

3. Connect the other ends of the RF Cables to the RF

Connectors on the antenna.

4. Slide the Protective Shroud down over the RocketM until it

locks onto the Rocket Mount Bracket.

Note: If you have trouble 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 only.

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 1.5" - 3.0" pole.

9. The antenna has an electrical downtilt of 3°. 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(18lb-ft) or less to avoid deforming thepole.
