GatesAir has broadened standards support for the Maxiva XTK exciter ahead of IBC 2026. The announced list includes DVB-T2, ATSC 1.0, ATSC 3.0, ISDB-Tb, Brazil's DTV+, DAB and DAB+, with transport-stream-over-IP input and real-time adaptive correction.

The design uses FPGA processing so modulation and features can be changed through firmware. GatesAir says the unit works with current Maxiva UHF and VHF transmitters and many legacy Harris systems, offering an upgrade route that can retain installed RF infrastructure.

Why it matters

A common exciter can reduce spare-parts and migration complexity for groups operating across standards or planning a phased transition. The announcement does not separate functions available at launch from licensed or future options, and it provides no public lab measurements for correction performance, switchover or interoperability.
