Setup Manual

Prior to installation, determine the specific
antenna location and type of mounting. The
transmission line should be kept as short as
possible so, when line-of-sight placement of
antennas allow flexibility, it is always desirable
to locate the equipment closer to the antenna.
Within the USA and Canada, antennas other
than those illustrated in these tables can be
used with this radio, but must be of the same
type (flat panel or solid parabolic), dimensions,
and gain as those listed in the table. Antennas
with gain less than 7.5 dBi are not approved for
use within the USA or Canada. Consult
governmental regulations or Proxim Corporation
for applications outside of the USA or Canada.
For further information regarding antenna
installation and adjustment, see “Installing and
Adjusting the Antenna” later in this section.
Note: Max BSU Tx (dBm) is the lesser
of 17 dBm and 36 - G + L
G is the antenna gain and L is the
transmission line loss.
Reviewing the Installation Process
The following is an overview of the installation
process to assist you in your planning activities.
1. Test Radios Back-to-Back and
Configure
▪ Use at least 60 dB and no more than 80 dB
attenuation and a short low-loss RF
transmission line to connect the two radios.
▪ Apply power.
▪ Verify configuration settings (through the
BSU Console) for proper configurations.
▪ Verify that the SU enters the network.
▪ Connect to services, if possible, to verify
network connection and configurations.
2. Mount Antennas
▪ Antenna height can be critical for path
clearance and line of sight.
▪ Ensure that antennas will not be blocked by
people.
▪ Antenna structure must be secure for wind
load and whatever climbing may be
necessary.
3. Run Transmission Line Route and
Egress, including Lightning Arrestors
▪ Use proper transmission line.
▪ Proper termination is critical, especially at
5.8 GHz.
▪ Be careful with the bend radius and never
kink the transmission line.
▪ Secure transmission line to structures; be
careful not to crush.
▪ A direct connection to the antenna feed is
ideal (if required, you can use a flexible
jumper at the antenna, a properly specified
90-degree connector/adaptor, or both).
▪ Weatherproof all outdoor connections when
completed with installation.
▪ If the transmission line is longer than three
meters, a lightning arrester located near the
RF Unit is recommended. If the RF Unit is
