It‘s your worst nightmare: the failure of a transmitter, combiner or antenna. At crucial times like this, systems with full redundancy are the unsung saviours of the day, and it’s just such a system, the new N+1 switch, that Spinner will unveil at IBC2010.

Designed to remotely control backup systems, the N+1 switch is designed to allow the operator to maintain complete transmission operation, even after a system failure. It does this by duplicating combiner systems, so a planned channel change is possible without interrupting the ongoing transmission in advance. Service work on the main or spare antenna after switchover is also possible. Spinner also envisages the N+1 in use for switching signals to an upper, and lower, half-antenna. To that end, modules are equipped with an additional switch and splitter with phase compensation.

At the same time, Spinner will also be showing its new high power compact splitter and UHF DVB-T 3dB high power coupler. The 3dB coupler can be used as a broadband coupler in CIB combiners or as a power splitter in antenna patch panels. Designed for a maximum sum power of 100kW, an optimised version with improved heat transfer can even sustain 120kW. The allowable RF peak voltage is 28kV.
