3.

Solder the ground wire to the ground-wire terminal lug supplied with the lightning 
arrestor. Juniper Networks recommends that you use 6-gauge cable for the ground 
wire. The ground wire must be properly earthed in order to provide adequate 
protection.

4.

Attach the ground-wire terminal lug, lock washer, and hex nut to the lightning 
arrestor, in the order shown in the figure below. 

Figure 3–4.  Attaching the Ground-Wire Terminal Lug, Lock Washer, and Hex Nut to the 
Lightning Arrestor

   

   

a.

Connect one end of the short RF coaxial cable to the WLA620 N-type connector, 
and connect the other end to the lightning arrestor.

b.

Connect one end of the 3m RF coaxial cable to the lightning arrestor, and 
connect the other end to the outdoor antenna. Continue with step 6.

5.

Connect the antenna to the WLA620 N-type connector using the RF coaxial cable 
provided in the antenna package.

6.

Apply weatherproofing tape to the antenna connectors to help prevent water 
entering the connectors.

Informational Note:  

To meet regulatory requirements, you must ensure that the external 

antenna specified with the set ap radio antenna type command exactly matches the 

external antenna attached to the WLA620 external antenna port.
