Installing the Antenna
1. Introduction
The Senao access point is designed to perform in a variety of
environments. Implementing the antenna system can greatly improve
coverage and performance. A good communication can only be
achieved with the right antenna. The antenna kits comprise numerous
components, including the antenna, connectors, mounting hardware,
antenna cabling, and in certain product boxes.
2.
Type of Antennas
The Senao access point may be bundled with several different
styles of antennas for use in the 2.4GHz range. Each type of antenna
will offer different coverage capabilities. As the gain of an antenna
increases, there is some tradeoff to its coverage area. Usually high gain
antennas offer longer coverage distances, but only in a certain direction.
The radiation patterns below show the coverage areas of the styles of
omni-directional and uni-directional antennas.
◆Omni-Directional Antennas
An omni-directional antenna is designed to provide a 360-degree
radiation pattern. This type of antenna is used when coverage in all
directions from the antenna is required.
Figure 1-1: Omni-Directional Antenna (top-view)
◆Directional Flat Panel Antennas
Directional antennas have many different styles and shapes. By
redirecting this energy, it has the effect of providing more energy in
one direction, and less energy in all other directions. As the gain of a
directional antenna increases, the angle of radiation usually
decreases, providing a greater coverage distance, but with a reduced
coverage angle.
Figure 1-2: Directional Flat Panel Antenna (side view)
3. Antenna placement
The advices below are basic concepts to install an antenna.
The distance between the antenna and transceiver should be
kept to a minimum to reduce signal loss.
To operate at optimum efficiency, antenna cable should be
kept as short as possible.
IMPORTANT NOTE:
FCC RF Radiation Exposure Statement:
This equipment complies with FCC RF radiation exposure limits set forth
for an uncontrolled environment. This equipment should be installed and
operated with a minimum distance of 20 centimeters between the
radiator and your body.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
4. Installing the 3dBi omni-directional antenna
4-1. Hardware Description
The 3dBi omni-directional antenna is a broadband antenna for the
2.4GHz frequency band featuring an omni-directional pattern with a
normal gain of 3dBi. Before you start installing the antenna, verify the
following items in the antenna kits or in the product package.

4-2. Mounting the Omni-directional Antenna
You can mount the 3dBi antenna to a ceiling for indoor use. This
antenna uses vertical polarization that is the most common type of
polarization for omni-directional antennas.
◆ Mounting to a ceiling
In most cases, these installations require a large coverage area.
Experience has shown that an omni-directional antenna mounting at
about 6 to 8 meter (20 to 26 feet) will typically provide the best overall
coverage. Of course this also depends upon the height of the ceiling,
material on the ceiling and ability to locate the antenna at this height.
The antenna should be placed in the center of the desired coverage
area. An open area will provide the best performance.
To mount the antenna to a ceiling proceed following steps：
1. Position the ferrule (item B in Figure 2-11) to the front of the bracket
(item H).
2. Place antenna mounting screws (item F) through the screw hole on
the bracket.
3. Use the lock – washers (item G) and nuts (item C) to secure the
bracket to the ferrule (item B).
Use a wrench to tighten the nuts and ensure the ferrule will be fixed
to the front of the bracket.
4. Feed the omni-directional antenna (item A) through the hole of the
ferrule (item B)
5. Push the antenna through the ferrule (item B) to the end. Place
screw (item E) to tighten the antenna.
Note：The hole of the antenna should be above the ferrule.(See
figure 1-4)
6. Attach the cable (item I) and Jack (item J) to the connector on top
of the antenna.
7. Place 3 screws (item D) through the holes to fix the antenna on the
ceiling.
8. Attach the other end of the cable (item I) to the access point or the
PC card of the access point.

5. Installing the 7dBi Flat panel directional antenna
5-1. Hardware Description
The 7dBi flat panel antenna is a broadband antenna for the 2.4GHz
frequency band featuring a directional pattern with a normal gain of
7dBi. Before you start installing the antenna, verify the following items
in the antenna kits or in the product package.

5-2. Mounting the Flat panel directional Antenna
You can mount the 7dBi MHz antenna to a wall. Our package
has a 180° stand and you can adjust the best angle you want. This
antenna uses vertical polarization that is the most common type of
polarization for directional antennas.
◆ Assembly the stand
To assembly the stand proceed following steps：
1. Put the strut (item D) through the hole of the panel for antenna
(item B) and panel for wall (item C).
2. Place 2 screws (item F) through these two holes.
3. Use two nuts (item E) to secure the panel for antenna (item B) and
panel for wall (item C). Complete set picture is in step 3

◆ Mounting to a wall
To mount the antenna to a wall proceed following steps：
1. Stick or screw the stand on the wall.
2. Glue the one-gummed tape in the panel for antenna (item B) and
stick the flat panel antenna (item A) together. Make sure that the
connector of the flat panel antenna points to the ground.
3. Attach the cable (item H) to the connector on the button of the
antenna.
4. Attach the other end of the cable (item H) to access point or the pc
card of the access point.
