              FM Omnidirectional circular polarization antenna (87.5-108 MHz)

                         

                                                  

 

 Type 100.509 (87.5- 99 MHz)

 Type 100.519 (97-108 MHz)

 

General: Double crossed dipole antenna with circular radiation offers the possibility of simultaneously utilizing vertical and horizontal polarization for better coverage especially in urban areas.                                              

Mechanical design: Radiating element is made of stainless steel according to DIN 1744 standard.     

Radiation pattern: Free space pattern circularity is ±1 dB and nearly the same in pole mounting.

Connector: With the appropriate connector, 7/8"EIA flange, it has a maximum input of 2 kW.

Standing wave ratio: The VSWR is guarantied to be lower than or equal to 1.35 across the whole bandwidth
