Features & Benefits

The R&S®HE300CE active directional antenna locates transmitters and interference sources when combined with portable receivers (e.g. the R&S®PR100)

The overall frequency range from 500 MHz to 7.5 GHz is covered by a log-periodic dipole array antenna structure with a distinct directional pattern. The antenna does not have to be tuned within its frequency range.

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®HE300CE can also be used in the vicinity of strong transmitters.

The antenna is mainly intended for vertical polarization, but can be rotated 90° to provide horizontal polarization for testing.
