VHF/UHF Antennas R&S®HE309 Active Vertical DipoleR
Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2014/2015
Its extremely large bandwidth, wide dynamic range and excellent sensitivity make the R&S®HE309 ideal for all receiving tasks in radiocommunications, detection and monitoring, where the focus is on small size, a minimum number of distribution and switching units and a high S/N ratio.
The broadband characteristics of the R&S®HE309 active vertical dipole are achieved through a combination of the active antenna principle with a special design of the pas-sive radiators.
When the antenna is used together with the R&S®HE314A1 and the R&S®HF214 antennas, horizontally polarized waves can also be received.
