ETS-Lindgren 3181 Broadband Mini-Bicon Antenna 500 MHz – 18 GHz
Description
The Model 3181 is a broadband 500 MHz – 9GHz (18 GHz) omnidirectional antenna with a radiation pattern that conforms to the CISPR-16 specifications. The Model 3181’s frequency range covers most wireless bands worldwide; it can also be used for surveying or spectrum monitoring when used with a portable spectrum analyzer.
Frequency Range
The Model 3181 as designed to have the lowest possible VSWR across its range of operation. The antenna exhibits better than 2:1 VSWR for most of its range, and never exceeds 4:1 above 1 GHz.
Radiation Pattern
The radiation pattern of the Model 3181 is omnidirectional in the H-plane. This means the antenna can receive signals from every direction around its axis.
Spectrum Monitoring
The Model 3181 can be used for EM Field surveying and spectrum monitoring. Its low weight design allows for use as a surveying tool, when connected to a portable spectrum analyzer. Optional weatherproofing is available for long term monitoring outdoors.
Features
- 500 MHz – 18 GHz Frequency Range. (The antenna is recommended for the 500 MHz to 9 GHz range but that data is supplied up to 18 GHz where it can be used for spectrum monitoring)
- Radiation Pattern Conforms to CISPR-16 Specifications
- Ideal for:
— Chamber Characterization
— Broadband Spectrum Monitoring - Omni-directional Pattern Conforms with CISPR-16
- Manual
- Weather-proofing
- Individually calibrated at 1 m per SAE ARP 958 at our A2LA accredited lab. 3 m calibration per ANSI C63.5 available at additional cost. Actual antenna factors and a signed Certificate of Calibration Conformance included with manual
