The Smartech 27OCFDV dipole belongs to the family of the Off Center Fed antennas.
It's the optimal solution for who has little space. Furthermore, the "inverted V" dipole does not require a rotor since it's an omnidirectional system.
The 27OCFDV developes all above the joint with the mast, so can be mounted also relatively close to the ground.
Thanks to its aluminum structure, the antenna can be installed on a single support, differently from wire dipoles (linear and "inverted V") which necessarily require additional hookings for the ends.
The antenna has 50 ohm resistive impedance and doesn't need impedance adapters. So, power rating can be also remarkable.
Since the assembly is done in 6 simple and fast steps, the 27OCFDV dipole is well suited for both base and portable use.
Gain: better than a 1/4 wave vertical. Wide bandwidth.
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.
