THE FM ISO-FREQUENCY SYSTEMS

 

SFN (Single Frequency Network) in FM (87,5-108 Mhz) analog transmission.

Unique revolutionary R&D since 1987 by our engineering dept.suppliing Highway-Motorway Nation-wide network to AUTOSTRADE spa on frequency 103,300 Mhz.

A simple way to cover the highway with the same FM service consist in a system that converts the RF FM modulated signal to optical and deliver it trough a dedicated optical fiber line.

A low power repeater station will convert again the signal to RF.

The Frequency radiation is achieved by directional antennas to cover the area with the dedicated service.

The FM ISO-Frequency systems is composed by:

Head station

1. Standard FM Transmitter Mono, low power 1W

2. Laser Transmitter for optical fiber

3. Rack and accessory, UPS, monitoring, pass band filter, etc...

Repeater Station

1. Optical receiver for fiber

2. Special FM amplifier 0dbm imput with active filter tuned on the ISO frequency.

3. Rack and accessory, UPS, monitoring, pass band filter, etc...
