Belonging to the High Performance product line, the 3-element Yagi-Uda 27Y3-DRK SmarTech is an antenna that guarantees maximum Efficiency, excellent Forward Gain and excellent Front/Back Ratio thanks to its low native impedance design.
The antenna is matched to 50 ohm with a shorted two-wire line matching system, a.k.a. hairpin, which not only transforms the feeding impedance to 50 ohms, but also makes the antenna a DC Grounded system.
This feature represents an important protection of the transceiver from electrostatic currents generated on the antenna.

The weight of approx. 5 kg allows agile and undemanding installations, even with rotors and supports for TV use, as well as use for temporary installations such as portable use.
The antenna is supplied in a single package with an overall length of approx. 200 cm and is accompanied by an assembly manual with detailed descriptions and explanatory drawings, such as to make installation extremely simple and fast.

The 3 elements 27Y3-DRK SmarTech can be installed in both horizontal and vertical polarization.
The antenna is also suitable for stack configuration, thanks to which it is possible to modify the global radiation solid also on vertical plane. For technical details and customized solutions, contact the SmarTech Technical Division.


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.



Null


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.

I took part in many contests in the same location and with different antennas but I have never achieved such excellent results all together, despite many competing stations having better antennas and positions.
