The Rohde HE314A1 is a turnstile antenna consisting of two Active Receiving Dipoles 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 HE314A1 can be extended for omnidirectional reception of vertically polarized waves by using, for example,
an Active Vertical Dipole HE309 mounted at the top.
