TetraPol Repeaters
380 / 400 MHz · band-selective and channel-selective · off-air, fibre and tunnel
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.
TetraPol Repeaters — what the line covers
TetraPol is the narrowband trunking standard used across European public safety — German BOS networks, French and Polish police, and several central European countries. It sits alongside TETRA in the same 380 / 400 MHz spectrum, which is why the receiver and filtering platform is shared. Our TetraPol line covers the band-selective and channel-selective configurations in off-air, BTS-coupled fibre and tunnel versions. Band, power, channel count and interface are confirmed per project, because certification follows the national rules of each target market rather than a single document.

+20 to +45 dBm, configured per project
- Off-air receive (wireless donor)

- Channel-selective (8 / 16 / 32 channels)
- Tunnel coverage
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.
TetraPol is within our product scope. Specific models are configured per project: tell us the band, the channel count, the output power and the target market, and we will confirm the configuration and the certification route that applies there. Certification follows national rules — German BOS networks, for example, are not covered by a single EU-wide certificate.
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.

The model numbers below follow our public model naming rules: form, band, power and bandwidth are settled, while exact parameters, certification status and lead time are confirmed per project.
| Model | Form | Band | Power | Bandwidth / channels | Typical use |
|---|---|---|---|---|---|
| KT-A-E-B3P37B | Off-air receive (wireless donor) | 380 MHz | +37 dBm | Band-selective (whole band) | TetraPol 380 MHz off-air band-selective repeater, +37 dBm. |
| KT-A-E-B3P40B | Off-air receive (wireless donor) | 380 MHz | +40 dBm | Band-selective (whole band) | TetraPol 380 MHz off-air band-selective repeater, +40 dBm, for campus and plant coverage extension. |
| KT-A-E-B3P37C-32 | Off-air receive (wireless donor) | 380 MHz | +37 dBm | Channel-selective (single channel) · 32 channels | TetraPol 380 MHz off-air channel-selective repeater, 32 channels, +37 dBm. |
| KT-A-E-B4P37B | Off-air receive (wireless donor) | 400 MHz (UHF, 350–470) | +37 dBm | Band-selective (whole band) | TetraPol 400 MHz off-air band-selective repeater, +37 dBm. |
| KT-A-E-B4P37C-16 | Off-air receive (wireless donor) | 400 MHz (UHF, 350–470) | +37 dBm | Channel-selective (single channel) · 16 channels | TetraPol 400 MHz off-air channel-selective repeater, 16 channels, +37 dBm. |
| KT-F-E-B4P37B | BTS-coupled fibre repeater | 400 MHz (UHF, 350–470) | +37 dBm | Band-selective (whole band) | TetraPol 400 MHz BTS-coupled fibre repeater, +37 dBm, for fibre pullback. |
Standard, form, band, power, bandwidth and channel count are read from the model number under our public naming rules. Cellular model numbers carry no standard or power segment — power for each band is set by the regulatory limit in the deployment market and by the coverage design. The models listed here are configurations that can be built per project, not stock items; for models with datasheets, see the product centre.
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.
