AM Broadcast Repeaters
675–1269 kHz · +50 dBm · high-power AM rebroadcast
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.
AM Broadcast Repeaters — what the line covers
High-power AM broadcast rebroadcast for medium-wave coverage extension — transmitter site fill, regional re-broadcast of a single programme, and retransmission where terrain blocks the primary transmitter. Not third-party certified yet; where a project timeline allows we can assess the certification path.
- 675–1269 kHz (MW band)
+50 dBm class (100 W)
- Off-air (RF)
Compatibility is stated for the cited model; confirm the exact combination against the model datasheet before ordering.
Models on this line
Parameters below are taken from the model datasheet. Where a figure has not been verified against the document body it is marked accordingly rather than estimated.
KT-R-A-BAMP50B
Internal model: KT-AM-B594-P50-B
- Covers the 675–1269 kHz medium-wave AM broadcast band
- +50 ± 2 dBm output — a 100 W class unit for regional re-broadcast
- Automatic level control holds output within ±1 dB at +20 dB input
- Group delay ≤ 5 µs, so programme audio is not distorted
- Off-air RF coupling

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}]Every 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. 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.
