Connecting the Antenna

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-400.

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.

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-400 should be used with all transmit antennas powered down.
