DAB Digital Audio Broadcast Repeaters
Digital audio broadcast · gap filling and re-broadcast · band and power on request
The TETRA and P25 product lines are not third-party certified yet. Where a project timeline allows, we can assess the certification path, lead time and cost against your specific band, power and interface requirements. If your tender explicitly requires existing certificates, tell us and we will be straight with you about what is feasible.
OEM private-label manufacturing and ODM design are both available. Regional distribution is not currently offered.
DAB Digital Audio Broadcast Repeaters — what the line covers
DAB is the European digital successor to FM broadcast, and in China it is being rolled out on the standard digital audio broadcast band. Coverage problems are concentrated indoors, in tunnels and at the fringes of a transmitter footprint — exactly where a low-power rebroadcast unit is the economical answer. Band plan, output power and channel configuration follow the national allocation for your market, so we confirm them per project.
- Per national DAB frequency allocation for your market
Configured per project
- Gap filling
- Programme re-broadcast
- Off-air RF coupling
Compatibility is stated for the cited model; confirm the exact combination against the model datasheet before ordering.
Models on this line
This line is configured per project rather than sold as fixed models. Tell us the requirement and we will confirm what we can supply.
DAB rebroadcast is within our product scope. Band plan and output power follow the national allocation for your market — send us the frequency and the coverage gap you need to fill, and we will confirm the configuration.
What we can confirm from the line: the bands listed above, band-selective and channel-selective variants, off-air / fibre-coupled / BTS-coupled forms, and MIMO options. Output power is set against the regulatory limit of the deployment market — China, the UK and the EU all differ.

How to read our model numbers
Every model encodes its standard, band, power tier, bandwidth type and coupling form. You do not need a lookup table to read it.
KT-{form}-{standard}-B{band}P{power}{bandwidth}[-{channels}]Trunking (TETRA / DMR / P25 / AM / FM)
KT-{form}-{3GPP band list}{bandwidth}[-{role}][-{BD/SD}][-{SISO/2T2R}]Cellular — the band code implies the generation, so neither standard nor power appears in the model. Bidirectional and MIMO are stated because they are different hardware.
No standard code and no power figure: the band codes give the generations (n28 = 5G NR) and output power is set per project against the regulatory limit for that market. Bidirectional (-BD) and MIMO (-SISO / -2T2R) do appear, because a duplexer and a second RF chain are hardware — omitting them would ship the wrong unit.
Every trunking segment begins with an explicit letter (form, standard, B for band, P for power, C for channels), so position carries no meaning and a model cannot be misread. Multi-band cellular models list full 3GPP band codes (n28, B3, W8 …) rather than a shorthand, because procurement has to confirm the exact bands — and the band code already states the generation, so cellular models carry neither a standard code nor a power figure. Fibre systems add a unit role (-MU master / -RU remote) because the two are different units.
Models already covered by a third-party certificate keep their certified names — renaming them would break the certificate. A full one-page reference covering every code is supplied with the quotation on request.
Tell us the requirement, not the model
Send the band, power tier, bandwidth type, coupling form, channel count and project timeline. If certification is required for your tender, say so — we will tell you what is realistic rather than quoting a lead time we cannot meet.
Full datasheets for every model are available on request.
