Figure 78: Attaching the Antennas
Step 1
Use your thumb and index finger to insert and tighten antenna 1 and antenna 3 in the middle antenna attachment slots,
as indicated in the figure.
While installing the antennas, first install antenna 1 and antenna 3 (this instruction is for the two antenna
Note
attachments present in the middle) and secure it completely. If you install antenna 2 and antenna 0 first (this
refers to the first and the last antenna attachments), there will be less space to insert your thumb and index
finger and therefore, you may not be able to secure antenna 1 and 3.
Step 2
Insert antenna 2 and antenna 0 in the first and last antenna attachment slots.
Step 3 After installing the antennas, adjust the antenna orientation by spacing out each of them equally until they are spread out.
This is important because it helps in getting higher RF performance.
