VHF/UHF Antennas R&S®HE300 Active Directional Antenna
Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2012/2013
The practical and very wideband R&S®HE300 active
directional antenna locates transmitters and interference
sources when combined with portable receivers (e.g.
R&S®PR100). The three exchangeable antenna modules
supplied with the antenna cover the 20 MHz to 7.5 GHz
frequency range. An additional module (R&S®HE300HF for
9 kHz to 20 MHz) is available as an option. The modules
can be plugged into the handle with the correct orientation
for vertical or horizontal polarization and then mechanically
locked in place.
A built-in, low-noise wideband amplifier can be activated
to enhance system sensitivity (active mode).
In passive mode, the amplifier is bypassed so that the
R&S®HE300 can also be used in the vicinity of strong
signal sources.
Two different models of the R&S®HE300 are available.
Model .02 contains an analog compass for bearing deter-
mination; model .03 is equipped with an integrated GPS
receiver and an electronic compass. When used with the
R&S®PR100 portable receiver, the potential target can
easily be located on a map using the triangulation feature.
