LINKnet™ OFR400 RF MODULES ! USER MANUAL

Printed: 01.01.20,12:34
Revision Date:1/20/01 11
• 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 that 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 10 dB. 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 100
Watts maximum. Please consult Kaval Telecom for assistance as required. 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. This is shown in the figure in the Introduction. The Indoor Antennae
are simple 1/4 Wavelength (0 dB Gain) types. They are used with KAVAL
TELECOM INC. 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. 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. Please consult Kaval Telecom for assistance as
required. These Antennae are to be installed such that no person can touch the
Antenna, or approach within 0.2 Meters.
ANTENNA INSTALLATION
WARNING
ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED
TECHNICAL PERSONNEL ONLY.
ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE
PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE
REQUIREMENTS, AND ARE NOT OPTIONAL.
ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON
CAN TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS.
ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO
PERSON CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2
METERS.
