A muscled antenna, that offers the pleasure of being first.
The Smartech 27Y5LHP belongs to HP (High Performance) family by Smartech, dedicated to very high performance designs.
Modeled for native low impedance, the antenna is matched to 50 ohm with an hairpin system (a.k.a. beta match). Antenna low noise and DC Grounded, free from electrostatic noise and shocks.
Thanks to the excellent manufacturing process and its high quality materials, the SmarTech 27Y5LHP offers properties of high strength and durability. The antenna is suitable also for hostile environments, such as corrosive coastal zones.
Antenna performances, shown by the characteristic radiation patterns, are obtained through a rigorous numerical optimization (with the innovative PSO algorithm) and verified instrumentally on the physical model. SmarTech antennas are made taking into account the effects of each component (insulators, capacity between bracket/element ... etc.), starting from the calculation stage. Thus, the final physical model has no distortion and functional inefficiencies.
The antenna provides excellent performance even in stack configuration. Below there is the optimized configuration for a 2x27Y5LHP in vertical stack.
For different configurations or installation requirements, please contact the Smartech Technical Division.
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.
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
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.
