FY 3BB 7/16
Transmitting Antennas

General. The FY 3BB Vertical Directional Antenna series is designed for FM Broadcast Band (87,5 –108 MHz) . Each antenna is made with stainless steel (FY 3XBB models) or resistant aluminium alloy (FY 3BB models) and composed of three vertical elements and a mounting bracket.

Excellent Performance for stereo and SCA operation.

Directional. The azimuth pattern is directional narrow lobe and normally can’t be modified by the mounting structure presence. Over 30 standard patterns are available.

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.

Broadband. Suitable for channel or broadband operations with multi-channel combiners.

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.

Water, icing, moisture protection. The input connector is protected against rain and icing by a special housing. The internal balun is also protected against water, icing and moisture ingress by a sealed housing.

State of the art mechanical design, employing the finest materials (stainless steel, non-corrosive aluminium alloy, marine brass, virgin PTFE) resulting in long life service.

Lightning resistance is guaranteed by the DC ground potential of the entire antenna.
