the unit and the possibility for injury if the unit
should become detached from its mounting sur-
faces for any reason.
Although signal boosters can operate for years
without being attended to, the unit will need to be
accessed by service personnel with troubleshoot-
ing equipment, such as digital multimeters and
spectrum analyzer or a laptop computer from time
to time. The location of the power source will also
have a bearing on the mounting location. SB II
uses external heat sinks and needs to be mounted
where there can be an unobstructed air flow over
the heat sinks fins. The SB II cabinet will stay warm
during normal operation so in the interest of equip-
ment longevity, avoid locations that carry hot
exhaust air or are continually hot.
Mounting
Figure 1 shows mounting hole dimensions and lay-
out for the cabinet. Mount the cabinet using 3/8”
(10 mm) diameter steel bolts (not supplied). We
recommend flat washers on both ends and a lock
washer under the nut. Nut and bolt mounting is pre-
ferred to the use of lag bolts. Use backer blocks
where necessary to spread the force over a larger
surface area. In areas of known seismic activity,
additional devices such as tether lines may be nec-
essary.
Because TX RX Systems, Inc. cannot anticipate all
the possible mounting locations and structure
types where these devices will be located, we rec-
ommend consulting local building inspectors, engi-
neering consultants or architects for advice on how
to properly mount objects of this type, size and
weight in your particular situation.
