1. Introduction
This guide is designed to provide the information needed to mount A8n Series Base
Station (BTS) at the site location. A8n series contains 3 variants:
1) A8n: contains A8n base station plus 4 external 2.4GHz 14dBi panel antennas. Each
panel antenna can adjust direction and tilt.
2) A8Ein: integrated base station, multi-beam 2.4GHz 19dBi antenna array for 80
degree sector coverage.
3) A8in: integrated base station, 14dBi antennas and RF cabling optimized for long
range 360-degree access coverage.
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… A
planning on IP network is also an important issue for network planning.

4. Mounting A8n 2.4GHz antenna and cable
connection
4.1. Introduction
1. The A8n AP has 4 external 2.4GHz panel antennas. The A8Ein and A8in has
internal 2.4GHz antenna. External 2.4GHz panel antenna gives you more freedom
to adjust the direction and tilting of each antenna. Internal 2.4GHz antenna is
easier for installation.
2. At the top of A8n, there are 8 N-female RF connector marked with 1-8. They are
grouped to 4 groups to connect to 4 external 2.4GHz panel antenna.
3. It is recommended to seal the A8n series RF ports with weatherproof materials to
prevent water leakage.

connection
4.2. Mounting of A8n 2.4GHz Panel antenna
Mount the 2.4GHz radio antenna to the pole. It is recommended that to install the
standard A8n 2.4GHz antenna with the RF ports facing downward, as shown in Figure
4-2.
Adjust the direction and down-tilt angle of the A8n 2.4GHz antenna to align, as shown
in Figure 4-3

4.3. Cable connection from A8n to 2.4GHz panel antenna
Connect RF cable from panel antenna port to A8n 2.4GHz RF port at the top of A8n.
RF port 1 and 2 of A8n must connect to the same panel antenna. The same for ports
(3.4), (5,6) and (7.8) which each pairs must connect to the same panel antenna. It is
recommended to connect the A8n port to antenna port according Figure 4-5
mapping.
It is recommended to seal the A8n series 2.4GHz antenna RF ports with weatherproof
materials to get the best performance according to the procedure in chapter 6 of
this document

6. Weatherproofing A8n Series Radio Antenna
6.1. Introduction
Sealing materials are applied to outdoor antenna connectors to accomplish several
goals. First and foremost is to prevent water from entering the connector. The second
reason is to protect the connector from gradual degradation due to UV radiation
and pollution. Sunlight and weather will oxidize metal surfaces and cause DC
resistance to increase on exposed mating surfaces. It is true that the RF cable
connectors are supposed to be weatherproof, but if left exposed to weather
conditions, they will tarnish and start to look rather ugly in a short time. A good taping
job will also prevent the RF cable connectors from loosening up, which is a common
occurrence for RF cables exposed to vibration and strong winds.
We recommend the following sealing materials for weatherproofing the antenna
connectors:
1. High-quality, all-weather, black plastic electrical tape, preferably 3/4” (19mm)
wide to make it easier to manipulate the tape around the A8n Series BTS radio
antenna ports. An RF port is often first wrapped with a layer of electrical tape to
make it easier to remove the butyl rubber layer. In addition, one or more layers of

electrical tape are used as a final outer wrap to provide UV protection. We
recommend the 3M Scotch Super 88 Vinyl Electrical Tape for this purpose.
2. High-quality, all-weather, black butyl rubber tape, preferably 3/4” (19mm) wide to
make it easier to manipulate the tape around the A8n series BTS radio antenna
ports. Butyl rubber tape is self-amalgamating - it chemically bonds to itself,
forming a strong, waterproof joint. A layer of butyl rubber tape is applied around
a connector joint to provide a weatherproof seal, often on top of a layer of
electrical tape. We recommend the Andrew Corporation butyl rubber tape for
this purpose.
Installation Tips
A few general rules about weatherproofing RF ports:
1. Always apply tape at temperature above 32 degrees F to ensure adhesion. When
working in cold weather, always protect your tape rolls by storing it under your
coat and next to your body to keep tape flexible. If the tape cannot stretch
elastically, it will not seal properly.
2. Do not stretch the tape to the point where it distorts. Only apply enough pressure
to get a smooth wrap.
3. Smooth each wrapped layer of tape with your hands to ensure proper adhesion.
4. Do not pull the tape to tear it - always cut the tape. A pulled tape will most likely
unravel, decreasing protection.

5. In warm climates where there will be long exposure to sunlight, it is a good idea to
wrap an extra layer or two of electrical plastic tape over the butyl rubber layer to
enhance UV protection.
6. For vertical runs of cable, the final layer of electrical tape should be wrapped
from the bottom to the top, and overlap about 50% of the width of the tape. This
will provide the same effect as shingles on a house. The water will run down across
the joints without going into the joints.
In order to properly weatherproof of the BTS radio antenna ports, they must be
prepared before the installation.
1. Cut the butyl rubber tape into 1/5” (5mm) by 4” (100mm) strips.
2. Wrap a strip of butyl rubber tape around the base of each antenna port in the
clockwise direction. Take extra care to make sure that the resulting butyl rubber
ring would not hinder the tightening of the RF cable connector around the
antenna port.
