Circular Polarization Wide Band FM antennas for High Power
These wide band FM antennas are entirely made of aluminum treated Alodine and particularly recommended for hight power transmitters. They are very resistant but lighweight, with PTFE insulator and stainless steel clamps and screws. They are demountable in several parts to 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.
