The R&S®HE314A1 is a turnstile antenna consisting of two active receiving dipoles connected via a 90° hybrid coupler.
The antenna is used for the reception of horizontally polar-ized 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 R&S®HE309E active vertical dipole mounted at the top.
Key facts ❙ High sensitivity ❙ Wide frequency range ❙ Omnidirectional reception of horizontally polarized waves ❙ Small size ❙ Ideal for mobile or semi-mobile receiving systems
