• 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 20 dBi. 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. Please consult Kaval Wireless 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.
• For the Cellular Uplink Band (824-849 MHz) the Roof Top Antenna or
Antennae for linking to the Donor Site(s) has the added restriction that the
Effective Radiated Power (ERP) must not exceed 7 Watts (+38 dBm). Thus, if
the AGC is set (as per the Carrier De-Rating Chart) to +28dBm as an example,
the maximum allowed Antenna Gain must be no more than 10 dBi.
• 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
WIRELESS 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. 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 Wireless
for assistance as required. These Antennae are to be installed such that no
person can touch the Antenna, or approach within 0.2 Meters.
