Turnstile Antenna Radiation Pattern. pattern of the antenna Whereas at the design frequency the maximum gain differential around the pattern was 103 dB the gain differential at 495 MHz is 221 dB and at 505 MHz is 251 dB The differential grows as we further depart from the design frequency resulting in bidirectional oval patterns rather than an omnidirectional pattern.

A turnstile antenna or crosseddipole antenna is a radio antenna consisting of a set of two identical dipole antennas mounted at right angles to each other and fed in phase quadrature the two currents applied to the dipoles are 90° out of phase The name reflects the notion the antenna looks like a turnstile when mounted horizontally The antenna can be used in two possible modes In normal mode the antenna radiates horizontally polarized radio waves perpendicular to its axis In axial.

iii ABSTRACT The Turnstile Antenna is one of the many types of antennas that have been developed to be primarily used for omnidirectional very high frequency (VHF) communication The basic turnstile consists of two horizontal halfwave antennas (halfwave dipoles) mounted at right angles of each Author Mohamed AlkhatibCreated Date 7/18/2016 112201 PMPublish Year 2016Title The Pennsylvania State University.

The Turnstile antenna is another type of array antenna The shape of this array symbolizes the turnstile which is used at the entrances of few places This antenna has a wide variety of military applications Frequency range The frequency range in which the turnstile antennas operate is around 30 MHz to 3GHz which belong to the VHF and UHF bands.
