Active omnidirectional reception of horizontally polarized waves

The R&S®HE314A1 is a turnstile antenna consisting of two Active Receiving Dipoles R&S®HE302 connected via a 90° hybrid coupler.


The antenna is used for the reception of horizontally polarized signals; the horizontal radiation pattern is optimized for omnidirectional reception.


The R&S®HE314A1 can be extended for omnidirectional reception of vertically polarized waves by using, for example, an Active Vertical Dipole R&S®HE309 mounted at the top.
