Antenna, Ultra-Wideband | EM-6945 | 500MHz – 25GHz

The Electro-Metrics EM-6945 ‘Vector’ is an Ultra-Wideband Log Periodic antenna that comes in a small, easily deployable handheld package. The EM-6945 has been optimized for peak efficiency across its entire frequency range while maintaining stable directional radiation patterns. It offers a consistent 5-8dBi of gain across the majority of its frequency range. The Vector is the ideal hand-held device for locating the origin of transmitting equipment. Perfect for SIGINT and multi-band communications applications or any other application where a small, rugged, high performance passive antenna is required.

A detented, pivoting handle with a built-in ¼-20 tripod mount allows for immediate polarity changes without any additional setup required.
