Global Invacom Quatro GTU Mark III

The FibreIRS GTU converts optical power to RF power (4 satellite bands and FM,DAB,DTT ). All units have built in AGC which allows a wide dynamic range of optical powers without affecting output power and quality. Two LED indicators allow the user to monitor the status of the unit.

Quatro GTU for use with a multiswitch as it has dedicated outputs for each of the satellite bands (Vertical Low, Horizontal Low, Vertical High, Horizontal High) and terrestrial.

Can be powered via the satellite outputs and used with either the Optical LNB or the ODU32.
