Bird AT-100 Antenna Tester

Connecting the Antenna
Antenna leads and the Field Strength Antenna are
connected to the test port. A known good RF cable can be
used to connect the antenna tester directly to a coupler box,
bypassing the antenna system lead. A female TNC connector
is provided. Other connectors are available, see Parts List in
the maintenance section for more information.
Special consideration must be given to the RF energy
present at the feed line of site antennas. At active sites, RF
energy from transmitters can be coupled to the antenna
under test. If large enough, these signals will cause
inaccurate measurements. For best results, the AT-100
should be used with all transmit antennas powered down.
WARNING
Live RF energy. Do not touch or ground the center
conductor of a live RF connection. Failure to
comply may result in equipment damage and
serious burns or death to personnel.
CAUTION
AVOID STATIC DISCHARGE
Use proper Electrostatic Discharge (ESD)
precautions to avoid static discharge when making
connections to the test port. Equipment failure can
occur if the test port is subjected to ESD.
CAUTION
250mW max. input
Exceeding the maximum input will damage the unit.
Do not connect transmitter output to the AT-100.
Damage can also be caused by testing antennas near
other transmitting antennas. If testing base station
antennas, first measure the power at the coax end to
be sure it does not exceed 250mW.
