3 Introduction
This chapter contains antenna installation and warning information for the LNKF100 Modules.
3.1 Antenna Installation

All antenna installation to be performed by qualified technical personnel only.
Antenna installation instructions and locations below are for the purpose of satisfying
FCC RF Exposure Compliance requirements.
Note! If multiple LinkNet™ Modules are used, the Instructions below apply to the
composite power output of all Modules when transmitting simultaneously.
The Roof Top Antenna or Antennae for linking to the Donor Site(s) is/are directional (high
gain) Antennae, fixed-mounted physically on the side or top of a building, or on a tower.
The Antenna Gain must be no more than 20 dBi.
Note! If multiple LinkNet™ Modules are used with output combiners into any one
Antenna, and/or multiple Antennae are used on one Roof Top, then the sum of
composite powers into all Roof Top Antennae must not exceed 20 Watts maximum.
The Roof Top Antennae location should be such that only qualified technical personnel
can access it, and that under normal operating conditions no other person can touch the
antenna, or approach within 10 meters of the antenna.
The In-Building Antenna connection is via a coaxial cable distribution system with signal
taps at various points connected to the fixed-mounted Indoor Antennae. The Indoor
Antennae are simple 1/4 wavelength (0 dB Gain) types. They are used with Powerwave
Technologies’ 12, 16, or 20 dB cable taps. As such the maximum EIRP will be at the first
tapped antenna, which will be 12 dB below the maximum signal level of the LinkNet™
(+40 dBm); +28 dBm, or 0.63 Watts EIRP. These antennae are to be installed such that
no person can touch the antenna, or approach within 0.2 Meters.
Note! If multiple LinkNet™ Modules are used with output combiners, then the composite
power output of all Modules transmitting simultaneously must meet this maximum
EIRP requirement.
