Circular Polarization Narrow Band FM antennas
Circular polarization tuned FM antennas, very resistant but light, entirely made of stainless steel. This antenna is factory tuned at any frequency within 87.5 to 108 MHz. It can be easily retuned on any new frequency inside the FM band with the simple aid of suitable instrumentation. The stainless steel is pickled with an electrochemical method that makes it uniform in color and eliminates the weld marks. All the metal parts are electrically grounded to prevent possible problems arising from lightnings .
For a correct working they must be mounted on a support pole not too big and if possible without other antennas or metal structures nearby. This antenna is particularly suitable for city installations where multiple reflections (multipath) are a problem and circular polarization it drastically reduces the negative effects.
