Products: AT-Series Antenna Testers
Bird’s AT-Series antenna testers give installers, technicians and engineers the ability to test antenna VSWR, match efficiency or return loss over an entire band or band segment in a matter of seconds.
APPLICATIONS:
- AT-100: Any 2-136 MHz service including SINCGARS tactical and airborne communication, Nav/Com, police, fire, HF amateur and emergency.
- AT-400: 80-520 MHz applications including aeronautical, land mobile radio, FM, TV, VHF and UHF amateur.
- AT-800: Any analog or digital 806-960 MHz service. Pre-programmed band segments for AMPS, NADC, GSM, PDC, and CT-2 cellular testing.
These compact, rugged testers are powerful and easy to use, yet provide complete control of test conditions. Menu driven, software-defined keys and digital keypad permit quick selection of operating mode and direct entry of test parameters.
A self-contained RF source drives the antenna- no external transmitter is needed. A built-in adaptable antenna jack mates a wide range of standard RF connectors. Plus, rechargeable batteries permit fully portable operation.
MODES & FEATURES:
- Swept Frequency Mode - Fast scans show VSWR, Match Efficiency or Return Loss across the entire band. A moveable cursor can be used to pinpoint scan frequency and digitally display the corresponding measurement value.
- Single-Frequency Mode - Can be used to optimize antenna performance and troubleshoot intermittent problems.
- Field Strength Mode - Verifies output of portable transmitters and hand-held transceivers having fixed antennas.
- Audible Indicator - Pitch varies with match condition. Keep your eyes and hand on adjustments and simply listen for the best match.
- Data Storage - Saves and recalls up to 12 scans in nonvolatile memory for long-term monitoring of antenna performance or degradation.
- Serial Communication Link - Optional software uploads data to a PC for analysis or storage.
- Portable - Lightweight, easy to carry, operates from rechargeable batteries, AC, or automotive adapter.
- Rugged - Designed for field use or test bench, and to meet the harsh environmental requirements of MIL-T-28800
Bird's AT-Series Antenna Testers test antenna VSWR, match efficiency or return loss over an entire band or band segement in a matter of seconds. Frequency range extended to 65 MHz; now covers NAV/COM and Markers. AT-400: 65-520 MHz for aeronautical, land mobile radio, FM, TV, VHF and UHF amateur.
AT-100: 2-136 for SINCGARS tactical and airborne communication, NAV/COM, police, fire, HF amateur and emergency.
