Using an External Antenna with the 170wl Radio Card

HP provides a variety of external antenna options for extending the radio range and shaping the coverge area of your access point by connecting antennas to your HP ProCurve 802.11g 170wl radio card . These antennas offer a number of different mounting locations, including indoor or outdoor, wall, ceiling, or radio mast.

This guide shows you how to install an external antenna for your 170wl radio card.

Professional Installation Required

Only the HP antennas listed in this guide are permitted to be connected to the 170wl radio card. You must use the appropriate antennas, cables, and where applicable, surge arrestors, for your given region. You are responsible for verifying local regulations or legislation that may impose restrictions on the use of specific antenna and cable combinations. For this reason, HP recommends that you consult with a professional installer who is trained in RF installation and knowledgeable in the local regulations prior to connecting an external antenna to your wireless radio product. It is the responsibility of the end user to ensure the antenna installation complies with the local radio regulations.

Pre-Installation Considerations

Planning the Installation

To determine the best location of your wireless access points and antennas, we recommend conducting a site survey before placing the devices in their final locations. For information on how to conduct a site survey, contact your local reseller.

WARNING Never install an antenna or construct a radio mast near overhead

powerlines.

Caution Never mount the access point outdoors to be near an external antenna. The

access point must always be installed indoors.

■ Installation Location - Plan the antenna’s position and orientation.

Consider these points:

• Use the antenna’s mounting bracket or other hardware, if included.

• For optimum performance, mount antennas as high as possible above any obstructions, and away from any signal absorbing or reflecting structures (such as those containing metal).

• Be sure there are no other radio antennas mounted within 2 m (6 ft).

• Consider the antenna’s radio coverage pattern so that it can properly cover the intended service area and not interfere with other radios and antennas.

• Because most antenna pigtail cables are a relatively short length, be sure to find a suitable mounting position for the antenna that is not too far from the access point. Alternatively, you may need to relocate the access point to achieve the desired coverage area for the antenna. Use an extension cable to span excessive distance between the antenna and the access point.

■ Omnidirectional Antennas - Consider these factors when selecting a

location for these antennas:

• Always mount the antenna in a vertical orientation so that the radio coverage pattern fills the intended horizontal space.
