The extremely large bandwidth, wide dynamic range and excellent sensitivity make the HE 309 ideal for all receiving tasks in radiocommunication, detection and monitoring, where the focus is on small size, a minimum amount of distribution and switching units and a high S/N ratio. The broadband characteristics of the HE309 are achieved through a combination of the active antenna principle with a special design of the passive radiators. When the antenna is used together with the Active Omnidirectional Antenna HE314A1 and the Omnidirectional Antenna HF214, also horizontally polarized waves can be received.

Features:

• Exremely wide frequency range sensitivity
• One active antenna instead of several passive antennas
