Example Antenna Systems
General. The FH 1C-BB N Low Power Circularly Polarized Antenna is designed for FM Broadcast. This antenna is entirely made with stainless steel and composed of one folded dipole and a mounting bracket.
Channel Operations. Suitable for single channel operations in the whole 87.5-108 MHz band. Easy field tunable.
Omni-Directional. The azimuth pattern is normally circular and can be modified by the mounting structure presence. As an option, the circularity of the horizontal pattern in presence of mounting structure can be factory tested.
Antenna systems. Stacking more antennas it's possible to obtain customized patterns, increase the gain and the power handling capacity according to user requirements. Custom patterns, electrical beam tilt and null fill are available upon request.
Easy installation. The standard mounting brackets are designed for instant installation on poles with diameters from 32 mm to 90 mm. Special brackets are available upon request.
State of the art mechanical design, employing the finest materials (stainless steel, non-corrosive marine brass, silver plated copper, virgin PTFE) resulting in long life service.
Lightning resistance is guaranteed by the DC ground potential of the entire antenna.
