Terminology

Directional Antenna - Is an antenna that radiates a signal in

one direction using a tight beam pattern. These
antennas come in several styles; yagi, panel and
parabolic.

db (decibel) - A unit of measurement for Antenna strength.

The higher the db rating the higher the strength of
the antenna.

Cable Loss - The loss in signal strength (db) due to the length

of your antenna cable. The longer the cable, the
greater the signal loss.

Fresnel Zone - An elliptical area on either side of the straight

line of sight that must also be clear for a long-range
wireless signal to work.

Gain - Amount of wireless signal strength added to a

standard signal normally measured in db ’s.

MC Card Connector - Antenna connector type used on Buffalo

Technology routers/AP’s, adapter and indoor antenna
products.

N type connector - Antenna connector type used on Buffalo

Technology outdoor antenna’s and coaxial cable.

Omni-Directional Antenna - An Antenna that radiates a signal

in a 360 degree radius horizontally and a signal
vertically with a degree spread that is dependent on
the antenna’s elements.

Basic Antenna Information

Wireless signals travel outward in an arc pattern from the
source. These radio frequencies lose significant signal strength
when traveling through walls, windows and other objects.
Materials like metal, stucco and thick concrete can actually
stop a wireless signal from passing through. Sometimes these
obstacles can be overcome by adding an antenna to your
wireless network.

Another issue is distance as the signal spreads outward from
the source it becomes dispersed and looses signal strength
and bandwidth. This is where an antenna helps the most in
increasing the overall signal and carrying it farther. An
average 8 dbi outdoor antenna can carry your signal up to 3/4
of a mile. Different Antennas have different signal patterns.

Locate the antenna connector sliding door on the

❶

rear of the AirStation.

Slide the door down on the rear of the AirStation to

❷

reveal the external antenna connector.
Note: On some AP's the door slides sideways.

Connect the antenna to the AirStation by plugging

❸

the male MC Card connector on the antenna cable
to the female MC Card connector on the AirStation.
Push firmly into place to ensure a good connection.

Run the cable down the left side of the AirStation

❹

and push behind the plastic tab to keep the antenna
from coming loose.

Connecting the Antenna

WLE-HG-NDR / WLE-HG-NDC

To install the WLE-HG-DYG and the WLE-HG-NDC you
first slide the rubber boot provided over the coaxial
cable and then connect the coaxial cable to the
antenna as shown below.

You then use the included vinyl tape and wrap the
connection with it. See picture.

Next wrap the vinyl taped connection with the
electrical tape provided. These steps are to help ensure
the connection stays stable and provide water
proofing. Important thing to remember is to start
tapping from the bottom up so that each layer is
overlapping this will help keep water out of the
connection see image.

After you have wrapped the connection you slide the
boot from the previous step over the taping. It should
fit flush against the bottom of the connection base.

8

Connecting the Antenna

WLE-HG-NDR / WLE-HG-NDC

Now connect the N-male to MC-card pigtail adapter to
the other end of the cable, as shown.

Now connect the MC-Card connector to your Buffalo
product.

If you are connecting this antenna outside a building
or enclosure and high on a pole you should include a
Lightning protector like the one shown below. Which
can be obtained from third party sources.

This device will connect between the antenna and the
coaxial cable you will then proceed with the other
steps as listed.

Antenna Mounting Brackets

WLE-KG-VPA / WLE-KG-VPB

When mounting an external antenna it is important to pay attention to the location you are
installing it. Please be aware that small incremental changes in elevation either up, down or side
to side can make significant changes in the signal quality. Several adjustments may be required
to achieve the best signal. You should test mount all antennas to check their signal patterns
before making their mounting permanent.

Connect the antenna’s MC card connector into the wireless device. Then adjust the antenna to
send/receive the best signal. When using the antenna on an adapter you can judge the signal
strength by watching the bars on the client manager as you adjust the antenna. When used on a
router/AP you can test it by placing a device with a wireless adapter at a low signal position and
then move the antenna on the router/AP to see if the signal improves.
