TETRA Repeaters
380 / 400 / 450 / 800 MHz · 1 W to +43 dBm · 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.
TETRA Repeaters — what the line covers
A complete TETRA product line covering four frequency bands and seven power tiers, in band-selective, channel-selective, off-air, fibre-coupled, tunnel and pico configurations. The line is not third-party certified yet; where a project timeline allows, we can assess the certification path against your specific band, power and interface requirements.

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.

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-{standard}-{band}{power}{bandwidth}{form}[-{channels}]Multi-band and multi-standard models use a group code after the standard (for example KT-L-B4Q-2BA = LTE, 380/900/1800/2100 MHz, 10–20 W, band-selective, off-air). A full one-page reference covering every code, including the models whose names are fixed by existing certificates, 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.
