V-Yagi antennas are an evolution of the traditional Yagi-Uda system, obtained by the modification of the typical Yagi planar shape.
The element V-configuration, along with their specific angle, give the 27YV2 SmarTech a remarkable F/B ratio and forward gain, considering its small dimensions.
Thanks to its particular weight and size, the antenna can be easly installed also in small spaces and on common supports (rotor/pole).
From the mechanical point of view the antenna is enough strong and resistant to remarkable wind loads.
The main structure is made of aluminum alloy EN AW-6060/82 UNI 9006/1 (Anticorodal 60/100), which provides excellent long-term durability against the most severe weather (ice, water, UV rays, fine particles, acid rain), and better resistance to heavy wind load.
The antenna is supplied with stainless steel parts AISI 304 (Inox Austenitic UNI / EN 10088) and steel S235JR2 (UNI 100 series), certified according to 2000/53 / CE + RoHs standards.
Element Insulators are made of Polypropylene PPC 5660, resistant to remarkable thermic excursions (certified for temperatures from -20°C to +130°C), with high load at break (ultimate tensile strength 25Mpa), excellent abrasion-resistant and volume resistivity > 1018
The antenna is made to obtain the maximum electrical efficiency, the best mechanical resistance and durability, thanks to its high quality materials. It is also suitable for installation in mountain areas and coastal (corrosive) areas.
SmarTech antennas are designed with the minimum necessary electrical/mechanical joints. So, parasitic resistances are the lowest possible so as to minimize unwanted RF dissipations.
In order to maintain its best performances, each Delta Loop is individually checked before shipment.
