The STR 3000 Base Radio rack contains the RF channels and related components for a simulcast remote site.
The cables shipped with your system were sized for a specific racking
configuration. Swapping equipment within racks or from one rack to another can
put excessive strain on cables and cause cable failures. Do not install additional
equipment or devices into the rack as this may have a negative effect on the
thermal performance of the equipment and result in reduced safety or reliability.
Overview of the STR 3000 Base Radio Rack
The STR 3000 Base Radio is the RF portion of the 800 MHz, digital-only, simulcast remote
site infrastructure. The STR 3000 rack includes from one to six base radios, multicouplers,
