NETGEAR ANT2405 Installation Manual

5 dBi Omni-directional Antenna ANT2405
Note: For optimal results in extending wireless range with antenna installations, consult a
qualified professional installer service for a site survey and proper installation. For a list of
devices approved by the FCC for use with the antenna, see the NETGEAR website at

Package Contents

The package includes:
• NETGEAR 5 dBi Omni-directional Antenna
ANT2405 including a 10 cm RG316 cable with a
reverse SMA connector for IEEE 802.11b or 802.11g
wireless devices
• Ceiling/wall mount bracket hardware
• Warranty card
• Support information card

Antenna Cable

The longer the antenna cable, the higher the signal loss (attenuation). This decreases range
and performance. For best performance, use a short cable between the antenna and the
wireless device. The shortest FCC-approved antenna cable is the NETGEAR 1.5 M
(ACC-10314-01) cable. For optimal performance, use a low-loss NETGEAR antenna
cable up to 10 meters long.
Specifications for 10 cm RG316 Antenna Cable (Included in the Package)
Type RG316
Length 10 cm (3.9 in)
External diameter 2.5 mm
Impedance 50 +/- 5 Ohms
SWR 1.5 maximum
Loss 138 dB/100 m (42 dB/100 ft) at 2.4 GHz
Minimum bend radius 2.5 mm (1 in)
Antenna Placement and Location
To maximize coverage and performance, place the antenna within the line of sight of your
wireless devices. Try to minimize partitions and objects that block the line of sight if
possible.
• For a ceiling installation, place the antenna in the middle of the coverage area.
• For a wall installation, place the antenna on an interior wall above cubicles (cubicles
generally include a metal foil). Ideal placement is 2 meters high.
• If the wireless access point, router, or gateway, is in an IT room, place the antenna
outside the room against a a wall and close to the ceiling.
The area close to, behind, or beside the antenna will be covered, because the dynamic
range of the WLAN transmitter/receiver and antenna is approximately 100 dB. Even with
20 dB to 40 dB or attenuation, the signal strength is still strong and communication is
maintained.

Installing the Antenna

Turn off your wireless access point, and connect your ANT2405 antenna. If your wireless
access point is new, follow the access point installation instructions. If you are upgrading
an existing access point, turn it on again.
