2.1.4 Proximity to power source
The indoor unit (CU) must be located within 20 feet (6 meters) of a power source, unless
the Hidden Cable kit is used. This kit includes a BIAS-T (power inserter) that allows the
system to be powered from a AC outlet located within 20 feet (6 meters) anywhere along
the coaxial cable.
2.1.5 Distance between DU and CU
Although you should separate the DU and CU as much as possible, the maximum
length of RG-6 cable that can be used to connect the two units is 164 feet (50 meters).
For greater DU to CU separation, RG-11 double shielded cable can be used to connect
the two units. Using RG-11 cable extends the maximum DU to CU distance to 328 feet
(100 meters).
Plenum rated RG-6 and RG-11 cable may also be used for installations in return air
ceilings, floor to floor riser use and elevator shafts. The maximum Plenum cable lengths
that can be used are 147 feet (45 meters) for RG-6 and 295 feet (90 meters) for RG-11.
Make sure the general location of the two units is within these limits. Use only Spotwave
Wireless approved cable.
Note: Although you should separate the DU and CU as much as possible, there is no
minimum cable length required between units for the SpotCell 2500Xe system.
2.1.6 Distance between main CU and auxiliary CU
The maximum cable lengths that can be used to connect two CUs is the same as that
for connecting a CU and DU (see Table 1). Maximum separation of the CUs and back-
to-back positioning will optimize system performance.
2.1.7 Orientation of DU relative to CU
If possible face the DU and CU in opposite directions, and back to back while
maintaining maximum separation. While not a requirement, some installations will
perform better if the units are positioned in this manner. This is generally more important
for an inside mounted DU than one mounted outside on a roof or an external wall.
