The excellent gain and remarkable performance make the SmarTech 6 el. Yagi a superior antenna for critical installations.
This antenna has been designed with the most modern and innovative optimization algorithms, also used for professional purposes. The numerical model has undergone an additional iterative optimization cycle until convergence was achieved between the model and the performance measured on the physical prototype.
The structure is made of high quality materials with excellent mechanical properties to give the necessary strength and resistance to wind loads.
Impedance matching is achieved through a hairpin (beta match) system, which provides DC grounding for the antenna. The system offers special protection to electronic devices against electrostatic shocks.
Low-noise antenna.
The SmarTech 27Y6L is also well-suited for stacking with a second 27Y6L. Further radiation patterns are provided (see attached charts) for the optimized vertical stack configuration (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 extreme temperature fluctuations. (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 designed for maximum electrical efficiency, superior mechanical strength, and long-term durability. It is also suitable for installation in mountain areas and coastal (corrosive) areas. However, other options are available if higher wind load capacity is required.
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.
What Our Customers Say

This is my superb 6 element SmarTech mounted on the pole. The structure is very strong, the best solution for my very windy location. I have been impressed for the large bandwidth, SWR was already centred on the frequency I wanted. Compared with my previous cubical quad antenna, I find signals enough stronger and the front/back & front/side attenuation also better. Happy for my new antenna, thank you all very much SmarTech. | |

The 27Y6L is an extremely performing antenna in transmission, as well as in reception, very resistant to wind ... in short: "it is the definitive antenna". | |
