3/27/2006 Hickory 2.4 GHz Non-articulating Dipole Specification

1. Introduction
This document describes the complete set of required specifications for a dipole
antenna for use with Cisco access points. In general, this antenna is a standard dipole,
about 4.4 inches long, built directly on a reverse polarity-TNC connector. In a break
from tradition, this dipole has NO articulating feature. It is designed to be as short as
possible. The antenna will operate in the 2.4 GHz band and should be built to operate
in an indoor environment.

2. Antenna Electrical Specifications
The electrical specifications for this antenna are summarized in Table 1 below. All
the manufacturer’s specifications should be reported in data sheet format.

Cisco Non-Operational Shock Test

Conditions: Temperature = 21 C, +/- 5 C, Humidity = 30-60% RH.

Product shall be subjected to one Trapezoidal Shock impact for each
direction (positive and negative) in each of 3 axes at a level not to
exceed the maximum peak acceleration values listed.

Weight MINIMUM Peak MAXIMUM Peak Min. Velocity

Trapezoidal Shock pulse generation is referred to ASTM D 3332.

Record VSWR at Minimum Peak Acceleration level and again at
Maximum Peak Acceleration level.

Pass Criteria: VSWR still as specified and no deformation or exterior
damage (at minimum acceleration) levels such that the product is
considered “un-sellable”.
