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 2Directional 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. 3IMPORTANT NOTE:FCC RF Radiation Exposure Statement:This equipment complies with FCC RF radiation exposure limits set forthfor an uncontrolled environment. This equipment should be installed andoperated with a minimum distance of 20 centimeters between theradiator and your body.This transmitter must not be co-located or operating in conjunction withany other antenna or transmitter.
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. ◆ Elements list (Figure 1-3) Element Description Quantity Item Omni-directional Antenna 1 A Ferrules 1 B Nut 2 C Screw (Long) 3 D Screw (medium) 2 E Screw (short) 1 F Lock-washers 5 G Bracket 1 H Cable 1 I Jack 1 J 4.

Figure 1-3 Elements list 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 5
6to 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. Step 3Step 2Step 1 Step 4 Step 5 Step 6 5 Step 7 Step 8

85. 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. ◆ Elements list (Figure 1-5) Element Description Quantity Item Flat Panel Antenna 1 A Panel for Antenna 1 B Panel for Wall 1 C Strut 1 D Nut 2 E Screw 2 F Gummed tape 2 G Cable 1 H Figure 1-5 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.
9 ◆ 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 Step 1 Step 2 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.
