Circularly Polarized FM Broadcast Antenna

PDF DATASHEET

LCX SERIES

General informations

The LCX Circularly Polarized Antenna series are designed for FM Broadcast Band ( 87.5 –108 MHz). Each antenna is entirely made with stainless steel and composed of two folded dipoles and a mounting bracket.

Broadband

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

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

By stacking more antennas it’s possible to obtain customized patterns, increase the gain and the power mhandling capacity according to user requirements. Custom patterns, electrical beam tilt and null fill are available upon request

Disassemblable

These antennas are disassemblable in order to reduce the shipment and stocking costs.

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 marine brass, silver plated copper, virgin PTFE) resulting in long life service.

Lightning resistance

It is guaranteed by the DC ground potential of the entire antenna.
