MATERIALS

The main structure of the antenna is made of aluminum alloy EN AW-6060/82 UNI9006 / 1 (Anticorodal 60/100), which gives greater durability against the most aggressive atmospheric agents (ice, water, UV rays, fine dust, acid rain), and a better resistance to the mechanical stresses of the wind.

SmarTech antennas are also supplied, depending on the models and specific mechanical requirements, with parts in Aisi 304 stainless steel (Austenitic Stainless Steel UNI / EN 10088) and parts in steel compliant with the resistance classes designated by the EN ISO 898-1 standard: 2013.

The antenna is engineered with high-quality materials and accurately dimensioned components, resulting in exceptional resilience even under significant wind loads.

Aluminum is a material with high resilience that can withstand significant loads and stresses without suffering from permanent deformation or structural failure. To ensure that an antenna structure maintains its resilience, it is important that the structure be designed to operate within the elastic mechanical field of the material. This means that the stresses placed on the antenna structure should not exceed the yield strength of its components and that the antenna can return to its original shape after being subjected to loads or stresses. By designing antennas with these principles in mind, SmarTech can ensure that all antenna parts remain resilient and maintain their structural integrity over time.

The insulators blocks are in POLYPROPYLENE PPC 5660, a material resistant to considerable thermal excursions (from -20 ° C to + 130 ° C), with high breaking load (tensile strength 25Mpa), good resistance to abrasion and volume resistivity> 1018

The antenna is designed to achieve maximum electrical efficiency and the best mechanical strength and durability, thanks to the quality of the materials used.

It is also suitable for installation in particularly aggressive environments, such as high altitude mountainous areas or coastal areas with a highly corrosive atmosphere.

SmarTech antennas are made with materials and technological solutions that minimize parasitic resistances (which produce unwanted RF dissipations) along the entire radio frequency signal path.
