1 Introduction
This guide is designed to provide the information needed to mount A8 base station (BTS) and
A8 antenna at the site location.
The document is applicable for hardware platform A8 R2 and the following models.
Product name : A8 802.11ab/g AP BS/Bridge AC
Model number : WA8011A-A
Product name : A8 802.11b/g AP BS AC
Model number : WA8011A-B
It is assumed in this document that a site survey has been performed before the site installation.
The appropriate antenna pole and BTS locations have been selected. It is a good practice to have
a document consists of a map and drawing illustrating the base station and poles locations,
antenna bearing/down-tilt, antenna height, etc… An planning on IP network is also an important
issue for network planning.
The user may need to refer the following document during A8 installation and Configuration.

6 Site Preparation
1. Prepare required tools, e.g. screwdriver.
2. Prepare a CAT5 (or higher) network cable for network connection of A8 base station.
Please make sure that the network connection between central office and the site is
properly connected.
3. Make sure that there is AC electrical power supply for A8 base station at the site.
4. Configure the A8 base station properly, e.g. assign correct IP address of A8 base station.
5. Prepare 8 x RF cables for RF connection between antenna and base station. Please refer
to the Section 12 – Recommendation on RF cable .

7 Mounting A8 antenna on a pole
1. Assemble the antenna with mounting kit according to Figure 6. Select the suitable screw
(Parts 11, 12, 14 & 15 in Figure 6) to fix the pole size (diameter).
2. Double check the upper and lower mounting as shown in Figure 7 and Figure 8.
3. Mount the antenna to the pole, as shown in Figure 9.
4. Adjust and measure the upper mounting to the desired downtilt degree, as shown in
Figure 10 and Figure 11.
5. Tighten the mounting kit by screwing the nuts.
6. The antenna should look like this after mounted on the pole,

10 Mounting A8 Base Station on the Wall
1. Use an electric drill to drill four suitable apertures on the wall. (It is strongly recommend that
mark the suitable positions on the wall by pencil before drilling)
2. Put the wall plugs into the apertures.
3. Place the metal plate on the wall such that the four holes on the metal plate match the
apertures you drilled before.
4. For each of the wall plug, use the self tapping metal screw with a flat washer (Part E in
Figure 4) to fix the metal plate, Figure 17.
5. The fixed metal plate is shown in Figure 17.
6. Following the steps on step 2 to step 4 of “9 Mounting A8 Base Station on the Pole”.

12 Recommendation on RF cable and Antenna Pole
RF Cable
A RF cable should be assembled with N-type male connectors at both ends. The length and
diameter depend on the site situation. Our recommendation is that the insertion loss of the RF
cable should not be greater than 1dB at 2.4GHz (for 802.11b/g) or 2dB at 5.8GHz (for 802.11a).
Figure 20. RF Cable
Antenna Pole Size
The height of the pole should be 1.5m to 2m, and the diameter of the antenna pole should be 25
to 55mm or 80 to 90mm.
The vertical separation between antennas and BTS should not be less than 0.2m.
