The SmarTech 27YC6 is an antenna that allows multiple configurations: can be used independently as a 3 element Yagi in horizontal polarization, or as a 3 element Yagi in vertical polarization.

A vertical directional antenna does not receive noise like vertical omnidirectional antennas since signals (or better, "noise") coming from unwanted directions (side, back) are strongly attenuated. This is a precious "plus" for vertical polarization activity, an invaluable advantage both for direct traffic and DX activity.

A misalignment of polarization of 90 degrees degrades signals up to 30 dB. So, owning an antenna that allows both polarizations meand being able to work with the maximum efficiency in both situatuins.

27YC6 can be used also in slant polarization (feeding appropriately both radiators). Slant polarization is particularly suited to situations where signals are not perfectly horizontal or vertical, so fading effects are strongly minimized.

Radiation patterns show an interesting lobe profile in vertical polarization. The E plane has a particular width over a wide range of elevations (take off angles), useful for both long path DX and short path E-sporadic mode.

This antenna has a light but strong structure, particularly resistant to very severe mechanical loads. Thanks to the choice of the best materials and the specific sizing of each part, the structure has a strong elasticity and resistance even to the most energic wind loads.



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.
