Fordray Product Information

Catalog

The LB-FTL FM Translator is an operational combination of Fordray's 15 Watt PLL FM Transmitter and our 800MHz STL Link Receiver, packaged in a wall mount cabinet. The LB-FTL has been designed for unattended mountaintop translation, receiving an 800MHz STL Link frequency and re-transmitting on the 87-108MHz band at up to 15 Watts.

Installation is simple with 2 attaching screws, 2 antenna connections and 240V AC power. Front panel LEDs indicate power and received signal. An internal meter indicates received signal strength for aligning the antennae and the cabinet may be fitted with a security lock to prevent unauthorised access to the unit's circuitry.
