VHF DAB+
Transmitters

ALPAN represents the new Compact transmitters line made by Itelco capable to deliver from 350W up to 1000W in DAB+.

The core of this line is the MEXII multimode exciter combined with the Thalna air cooled amplification modules structure.

The integration of technologies related to MEX and Thalna lines allow to reach excellence levels in compactness, modularity and redundancy, well applied to the design of the transmitter as well as of the cooling system.

The homogeneity among all product lines and the manufacturing process optimization allow Itelco  to be extremely competitive, meeting the customers’ needs in terms of operating costs reduction, ease of maintenance and spare parts management.
