Installation and Operation Manual
REMOTE AMPLIFIER INSTALLATION
The collector base unit includes internal GPS and cellular antennas and a connection for the external remote amplifier / antenna
assembly (labeled “RF” in Figure 3). The remote amplifier / antenna assembly should ideally be mounted at an elevated location
to achieve superior range.
Note:
The antennas must be oriented vertically for proper operation, with the cellular modem antenna pointed upward.
Use up to 250 feet of type LMR-400 or equivalent cable to connect the two units. Greater lengths may be possible, if required,
by using higher performance cable. The matrix below lists supported maximum coaxial cable lengths based on type.

Consult Mueller Systems engineering for additional details.
The standard 8dBi antenna assembly includes a bracket that may be mounted to a pole, tower or solid surface using the same
mounting techniques as the collector base unit. See Base Unit Mounting Options. The optional 6dBi antenna shall be mounted
on the amplifier bracket as shown on the following page.
Note: All coaxial connections should be protected from weather effects by following the wrapping procedure shown in Appendix II.
If replacing collector antenna equipment, please reorder the original equipment. If modifying the antenna
configuration of your collector
you must use an antenna tested and explicitly approved by Mueller Systems
, or
all warranties will be voided.
