BelAir100SN Physical Description
This chapter provides a physical description of the BelAir100SN and its
associated hardware.
The BelAir100SN is an integrated radio product requiring only a connection to
a suitable power source.
Without antennas and strand mounting brackets, the BelAir100SN is
approximately 8.5 inches (21.6 cm) high, 15.5 inches (39.4 cm) wide and
7 inches (17.8 cm) deep. It weighs 29 lbs (13.2 kg). See Figure 1 on page 4.

AC Power Supply
Specifications
The BelAir100SN accepts an AC input power in the range of 40 VAC to
90 VAC -0% +10% with a quasi-square wave. The frequency range is 47 to
63 Hz. The typical current draw is less than 1 A.

AC Power Source
The BelAir100SN draws its AC power from plant power through its KS
threaded power interface. The BelAir100SN includes an industry standard GRS
connector that mates with a coaxial cable terminator with a KS interface for
cables of the following sizes: 0.412, 0.500, 0.625, 0.750, 0.875 and 1.000 inches.
A KS to F-type adapter can also be used. The GRS connector provides two
points of contact for a robust AC power connection.

Infrastructure Requirements for the BelAir100SN
This section describes the infrastructure that is required at the location where
BelAir100SN units are installed:
•“Protective Earth Ground” on page 6
•“AC Power” on page 7
•“Lightning Protection” on page 9
•“DOCSIS” on page 9
•“Ethernet” on page 13
•“Antenna Type and Placement” on page 14
Any identified specific third party parts are recommendations or examples only.
Substitution of equivalent parts is permitted. (If you are unsure of the
equivalency of a certain component, contact BelAir Networks.)
Protective Earth
Ground
For safety and functional operation, each BelAir unit must be connected to a
reliable earth ground before electrical power is applied to it. Special attention
should be made when installing the ground and connection of the ground wire
must follow local and national wiring codes. If multiple BelAir units are installed
at a single location, then each BelAir unit must be connected to the same
ground point.
The BelAir100SN is powered by the coaxial cable and is considered grounded
where connected to the cable shield, as required by US National Electric Code,
section 820-41. In addition, installers may wish to bond the BelAir100SN
ground to the messenger wire. To do so, the additional connection is to a
1/4 inch (approx. 6 mm) ground terminal with screw. Figure 2 shows the
location of the ground point and the ground terminal. Installers should follow
normal practices when grounding the unit. Installers should verify that all
grounding requirements listed in this document have been met.
Warning — Protective Earth Ground
Failure to connect the protective earth ground can result in a
shock hazard.

AC Power The BelAir100SN accepts power in the range of 40 VAC to 90 VAC (-0% to
+10%) from a quasi-square wave cable UPS power supply. The BelAir100SN
also requires that the cable UPS power supply limits its output current to 30 A.
Installers must ensure that the supplied power meets these requirements.
The BelAir100SN contains a permanently attached female KS threaded power
interface (Corning Gilbert part number G-EXT-1.5-SC-T). This connector can
connect with an industry standard GRS KS male threaded connector to accept
cables of the following sizes: 0.412, 0.500, 0.625, 0.750, 0.875 and 1.000 inches.
The mating connector accepts 0.065-inch to 0.75-inch pins trimmed to
0.5 inches. Figure 3 shows the female KS connector.

Figure 3: KS Connector
A KS to F-type adapter can also be used. See Figure 4. The customer is
responsible for supplying the appropriate coaxial cable terminator with a KS
male interface or the equivalent KS to F-type adapter. BelAir Networks
recommends using Corning Gilbert part number GF-625-CH-S-T which is
designed to work well with the BelAir100SN female KS threaded power
interface.

Professional installers with appropriate credentials and experience are
responsible for installing coaxial cable terminator or the KS to F-type adapter
onto the cable power supply using industry and corporate standard procedures.
Lightning
Protection
BelAir units are not designed to survive a direct lightning hit. However, they are
intended to withstand the voltage and current surges induced from nearby
lightning activity.
The BelAir100SN is designed to sustain multiple 6 kV/3 kA lightning surges
without damage or loss of operation. The BelAir100SN does not require
lightning protection except when an external antenna is installed more than
3 feet (approx. 1 m) from the unit.
In this case, you must use lightning arrestors to protect the external antennas
ports. When lightning arrestors are used, they should be located within 3 feet
(approx. 1 m) of the BelAir100SN unit and must be grounded to both the unit
and protective earth ground. The N-type connector may be used to complete
the ground connection.
DOCSIS BelAir100SN units contain an embedded Hitron DOCSIS 3.0 cable modem,
model number BRG-35502, providing connectivity to a host network, such as
the Internet.
The cable modem is accessed directly through the GRS connector that is used
for both power input and as a DOCSIS RF interface. The cable modem is fully
DOCSIS 3.0 compliant and designed for use with 75 ohm cables.
The standard input range of a cable modem is -15 dBmV to +15 dBmV for
DOCSIS 3 and 17 dBmV for DOCSIS 3. The BelAir100SN implements
independent 0 to 20 dB digital attenuators in both upstream and downstream
paths.
