Installation
1.
Remove the existing antenna from your
Wireless Device or Wireless PCI Card on
your Desktop Computer. Make sure the
antenna connector on your wireless
device is a Reverse SMA Jack.
For Wireless brands that do not come
with Reverse-SMA Jacks, the HA12W
includes a TNC Connector Adapter*.
Other type of adapters can be purchased
directly from Hawking.
*TNC connector usually works with most
Linksys®and Cisco®Wireless Devices.
2.
Locate the Antenna cable from the
packaging and connect the side with the
“Silver” colored connecter to the Window
Antenna. Connect the side with the
“Gold” colored connector to your Wireless
Device.
If the TNC Connector Adapter* is
needed, attach it to the “Gold” colored
connector on the Antenna cable, and then
plug it into your Wireless Device. Make
sure all the connectors are tight and
secured.

Device
b. Connect the “Silver” colored connector of

I. ANTENNA TERMINOLOGY
dBi (decibel): Used as a measurement unit for antenna strength. The standard
factory antenna strength for 802.11b/g wireless products is 2dBi. A higher dBi
level from the antenna signifies a more powerful wireless signal.
Omni-Directional Antenna: The antenna covers a 360° radius on plane level or a
flat surface. It emits stronger signal in a slightly smaller angle (vertically)
comparing to the Directional Antenna. The Omni-Directional is great for Wireless
Access Points that serve multiple computers in different locations.
Directional Antenna: The Antenna emits a direct signal, approximately 80° angle
on a flat surface , but wider coverage vertically. Directional Antenna are very
effective on both Access Points and Network Adapters (such as, Wireless Bridges,
PC Cards, USB Network Adapters etc...). Normally, it is reconmended to install
two directional antennas to optimize the performance. The extended range may
reach up to 2750 ft.
Reverse SMA Plug: Standard connector for a removable external Antenna. Most
wireless Access Points and Routers come with detachable antennas. Reverse SMA
plug is on the end of antenna connector that screws into the wireless device.
Reverse SMA Jack: Connector on the wireless device
side (Access Point, Router, PCI Card) Reverse SMA Plug
screws into the Reverse SMA Jack.

II. BASIC SETUP AND OPERATION
Below diagram is an example of a basic wireless Network.
Radio frequencies lose signficant signal strength when travelling through
concrete and especially metal walls. Because of the wall in front of the
Wireless Desktop room, the wireless signal is weak (A) and can not reach the
room with a wireless desktop. To solve this problem a Hi-Gain Indoor
Directional Antenna is set up to direct wireless signals out the door towards
the opposite wall, then bounce the signal to the room with the desktop.

III. OBTAINING OPTIMAL ANTENNA PERFORMANCE
Obtaining one antenna or two antennas?
Depending on your wireless application, you may need two antennas,
one on each end to optimize the signal. If you have an Access Point in
a small environment, i.e. home, with multiple users in different
locations, it is more cost effective for you to use one Omni-Directional
Antenna. However, in areas that recieve poor coverage, you may need
a Directional Antenna to amplify the signal from the receiving end, i.e.
Client side.
For extended wireless range, it is reconmended that you use two
Directional Antennas facing each other. If only one Hi-Gain Antenna
applies to one end and a normal (manufacture standard) antenna on
the other end, the result may not be as great as using two antennas.
The Hi-Gain side may send out a signal quickly, however, the other
end (manufacture standard side), may not have the strength to send
back the signal instantaneoulsy.

III. OBTAINING OPTIMAL ANTENNA
PERFORMANCE
(Con’d)
HA12W: Hi-Gain 12dBi Directional Window Antenna
To obtain optimal distances, the two antennas must be directly facing
one another with little or no obstructions interfering with the signal (if
possible a clear sight from one end to another.
NOTE: Many factors in the environment may affect your wireless
range. Different wireless devices may have stronger signals than
others which may derive varying performance results. For example,
the wireless output power on Access Points may vary from one brand
to the next, which would create different results. These published
results were obtained using HAWKING TECHNOLOGY wireless devices
that are tested to obtain the highest performances with HAWKING
TECHNOLOGY Hi-Gain Antennas.
Caution: This equipment complies with FCC radiation exposure set
forth for an uncontrolled environment. In order to avoid the possibility
of exceeding the FCC radio frequency exposure limits, human proxim-
ity to the antenna shall not be less than 1 foot during normal opera-
tion.
