FM BROADCAST TURNSTILE ANTENNA
SCFM4 87.5-108 MHz 6 dBi. Gain


SCFM4 FM Broadcast 4-Bay Antenna offer classical choice of antenna configuration with CIRCULAR or DUAL linear polarization, improving the broadcast of mono and stereo signals, particularly in hard zones such as conurbations and mountains.


Design & Construction:

A pair of dipoles are arranged in a 4-Bay turnstile configuration and a harness cable feeds both the dipoles to achieve desired circular or dual (cross) linear polarization.

SCFM4 FM Broadcast 4-Bay Antenna have low VSWR and high gain covering the complete FM broadcast band from 87.5 MHz. to 108 MHz. The dipole arms are mounted on a tubular boom made of high strength aluminum alloy.

SCFM4 FM Broadcast 4-Bay Antenna are supplied with dismantled dipole arms for easy handling and transportation and are assembled at site with simple hand tools.


Radiation Pattern:

With Bipolar structure and absence of parasitic elements, SCFM4 FM Broadcast 4-Bay Antenna guarantee a uniform radiation pattern over 360 degrees in horizontal plane. By using Reflector, the antenna radiation illuminates 180 degree sector, with 6 dBi. increased antenna gain.


Stacking:

The 4-Bay stacked arrayed results in higher gain of 6 dBi.


Power Divider:

6dBi. Power divider is a standard accessory, included with the antenna, for circular polarization.


Installation and Mounting:

These antennas are mounted on top of a square/triangular lattice antenna tower for uniform Omni directional coverage.
