Active omnidirectional antenna for horizontally polarized waves

The R&S®HE314A1 is a turnstile antenna with two active receiving dipoles connected by a 90° hybrid coupler. The antenna is used for receiving horizontally polarized signals and the horizontal radiation pattern is optimized for omnidirectional reception. The R&S®HE314A1 can be expanded for omnidirectional reception of vertically polarized waves with an R&S®HE309E active vertical dipole mounted on top.

Features & benefits

Wide frequency range

Saves money and maintains performance 

The R&S®HE314A1 covers the very wide frequency range from 20 MHz to 500 MHz, saving cost and space for mounting a multiple antenna system.

Omnidirectional reception of horizontal polarization

For detection of signals from different directions and better monitoring results

The R&S®HE314A1 is a turnstile antenna with two active receiving dipoles. The two horizontal dipoles are combined using a 90° hybrid coupler to produce an omnidirectional radiation pattern and improve monitoring performance.


When installation space is limited

Thanks to its sophisticated design, the R&S®HE314A1 has a maximum lateral dimension of approx. 1 m, making it suitable for installations where space is limited.
