INSTALLATION

dB

nstallation

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 HAI8DD
includes a TNC Connector Adapter*.
Other type of adapters can be purchased
directly from Hawking.

*TNC connector usually works with
Linksys® and Cisco® Wireless Devices.

2. Connect the

your Hawking wireless device. Screw in
the antenna connector on the end of the
cable from the Dish Antenna.

If the TNC Connector Adapter* is
needed, attach it before connecting the
antenna cable to your device. Make sure
the connectors are tight and secured.

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.

I. BASIC SETUP AND OPERATION

Below digram is an example of a basic wireless Network.

(A)

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 room with the desktop.

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 differents
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.

II. OBTAINING OPTIMAL ANTENNA

PERFORMANCE

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.

Con

Up to 5,000 ft

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 proxim­ity to the antenna shall not be less than 1 foot during normal opera­tion.

It is very easy to remove your original antenna. Simply, take your
wireless device, whether it be an Access Point, Bridge, Wireless PCI
Card, USB Adapter etc., and check to see if it has a removable
antenna. To determine whether your original antenna is removable,
examine the base of the antenna to see if it is a "screw on" type or a
non-removable type.

To remove your original antenna, hold it by its base and unscrew
firmly by turning it counter-clockwise until the antenna is seperated
from the connector. After it has been removed, take your Hawking
Hi-Gain Antenna connector and screw it (clockwise) onto your wireless
device.

After you have firmly attached your Hi-Gain Antenna, place it in a
location where it will achieve optimal performance.

. CABLE LOSS

Cable loss is the loss in signal strength (dBi) due to the length of your
antenna cable. Different types of Hi-Gain antenna cables have
different rates of cable loss. However, in all cases, the longer your
antenna cable is, the more signal strength (dBi) you will lose. This
table lists the specific antenna model, its cable type and the amount of
dBi lost per meter of cable:

As you can see from the chart, depending on the type of cable, there
is a varying range of cable loss per meter.

Measuring exact dB loss due to cable: (3.28 ft = 1 meter) Conversion rate
HAC10N is 10ft long. It has a cable loss of 0.26 dBi per meter.

Simple conversion shows that the use of this cable will result in:
10 ft (Cable length) / 3.28 (conversion rate) = 3.05 meters

3.05 meters x 0.26 (cable loss per meter) = 0.79 dBi

Therefore, when attached to an 9dBi Outdoor antenna, the actual
signal strength will be 6.32 dBi (Calculation: 9.0 - 0.79 = 8.21)
The HAC30N is a 30ft cable and would result in a cable loss of three
times the amount the HAC10N. (0.79 x 3 = 2.37 dBi cable loss)

When attached to the same 9dBi Outdoor Antenna the resulting actual
dBi is 6.63 dBi. This is a significant difference.

Please be sure to check the amount of cable you need and use the
shortest length possible to keep your signal strength at the highest
level.
