These wide band broadcast antennas for Circular Polarization FM are very resistant and entirely made of Aluminum treated Surtec650 with PTFE insulator, they are demountable in several parts for facilitate the shipping. 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. To increase the gain and therefore make it more directive is available a rear reflector and it also can be installed at a later time.
