Due to the variations of system layouts and requirements it is not possible to have one
procedure that will suffice every installation. You are strongly advised to acquire the services
of an RF system designer to calculate your antenna isolation requirements.
Ensure that your antennas are at the maximum possible distance apart. Do not place
antennas in close proximity to each other; otherwise you will activate the oscillation
detection process.
Coax cables should be low loss 50 ohm, and suitable for 1850 to 1915 / 1930 to 1995 MHz
band frequency.
Antenna connections should be clean and moisture free. Do not spray lubricant into the
connectors as this prevents the signal traveling through the coax. Use a cleaning solvent
that has no oil and does not leave any residue. High quality oil-less contact cleaner is
suitable.
All coax connectors must be water tight and wrapped with water proof tape. Any moisture
in the connectors will degrade or eliminate the signals.

ANTENNA CONNECTIONS ON THE APEX1933
The APEX1933 can be installed indoors. If mounted indoors ensure there is no elevated
room temperatures and free flowing air for cooling of the repeater.
Connect the antenna that is aimed at the Cell Tower to the bottom left side N connector.
Connect the antenna that is aimed towards the Area Fill (target site) to the bottom right
side N connector.
Connect your Ethernet cable to the connector socket located on the left side of the power
on LED light.
NOTE; Water proof boot cover for the Ethernet connection, contact your Repeater supplier.
2.4.10
ADJUSTING REVERSE LINK MAXIMUM POWER LEVEL.
Additional protection is gained if the reverse link maximum power level is adjusted to
prevent the possibility of sudden unwanted high input RF levels. This can happen in various
ways, mobile cellular vehicle boosters coming within range of the cellular repeaters,
malfunctioning cellular phones, or other stray signals.
The APEX1933 has an adjustable Maximum allowable RF Power limit. The maximum
allowable RF power limit is 33dBm. The digitally controlled attenuator will not permit RF
signal levels greater than 33dBm.
The user can decrease the maximum allowable RF transmit power from 33 dBm to 0.0dBm.
The microprocessor controlled digital attenuator will maintain the preset allowable RF
transmit power limit regardless of unwanted high input signal levels.
