Optimized Wideband Antenna (OWA), fed directly with a 50 ohm cable. The 27Y6S has been designed with NEC-based software, using integral method of moments MoM (Method Of Moments), and optimized with heuristic algorithms (PSO). SmarTech numerical modeling takes into account the presence of insulators, boom and joints, so as to eliminate radiation pattern distortions.

Prototype stages are realized by iterative cycles of measurements and optimizations, until the convergence between numerical model and performance measured on the physical model.


27Y6S 6 el Yagi SmarTech


The antenna is manufactured with top quality materials having excellent mechanical properties. Thanks to a specific sizing of each part, the resulting structure is strong but not rigid. Each part is optimized to work entirely within their own distinctive elastic field.

This antenna is also excellent for stack installations. With a second 27Y6S is reached a forward gain of abt. 18 dBi and an F/R of 24 dB or better (see stack graphics). For different configurations or installation requirements, please contact the Technical Division of Smartech.




MATERIALS

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 antenna is individually checked before shipment.


Costs include proper packaging, completion of customs documentation and shipping tracking 24/7. All products are shipped with the most important and reliable international couriers.

Since I have this new antenna, stations from America and Pacific are stronger and easily workeable. When I switch to the vertical signals are 5-6 points lower and noise is higher. Often I hear stations with the yagi wich totally disappear with the vertical antenna. It's 3 years the antenna is on my roof and still perfect. Bye!
