Overview
The TD-A9100 is a UHF FM two-way radio documented strictly from its published specifications. It covers UHF 400-470 MHz with 16 channels at 10 W high or 5 W low power, and it is built for a fixed, small channel plan rather than weekly reconfiguration.
Positioning and role
- Type: UHF FM two-way radio, described only from published specifications.
- Band and channels: UHF 400-470 MHz with 16 channels.
- Intended use: a fixed, small channel plan rather than a radio reconfigured every week.
- Power choice: 10 W high and 5 W low, trading reach against battery drain on one unit.
Channel and RF
- Channel spacing: 12.5 kHz or 25 kHz.
- FM modulation: 8KF3E at 12.5 kHz and 16KΦF3E at 25 kHz.
- Modulation limits: 2.5 kHz at 12.5 kHz spacing and 5 kHz at 25 kHz spacing.
- Narrow or wide: the same radio is configured to suit the channel plan in force, which installers and licensing engineers check first.
- Operating mode: one-frequency simplex or different-frequency simplex, so users take turns, the normal pattern for work-group traffic.
- Air interface: analog FM throughout with no digital air interface, so plan it as an FM unit.
Electrical and receiver
- Power: DC 7.4 V (+20%) working voltage from a battery rated 66 hours average working time.
- Stability and antenna: frequency stability ±1.5 ppm and antenna impedance 50 Ω.
- Transmitter: FM noise -40 dB and audio distortion 3%.
- Sensitivity: -124 dBm at 12 dB SINAD, for holding a weak signal cleanly.
- Rejection: intermodulation, adjacent-channel selectivity and spurious suppression each at 60 dB, to reject the channel next door.
- Audio output: 1000 mW rated output with 3% typical rated distortion.
Form factor and installation
- Compact battery unit: the published data describes a battery-powered unit rated for long shifts away from a socket.
- Packing list: host, antenna, battery, back clip, adapter and charger.
- No dash kit documented: our documentation does not describe a vehicle dash-mounting kit.
- Catalogue placement: listed in this section because the source catalogue places it here, and the copy follows published data only.
- In-vehicle use: tell us if the application is in-vehicle and we confirm the mounting and power accessories supported.
Ordering and OEM
- Band: documented at UHF 400-470 MHz; confirm the version against the licence held.
- Shared channel plan: check the 400-470 MHz FM plan if the radio must work with existing handhelds.
- Licensing: business channels are licensed locally by the operator or importer.
- Technical documentation: we supply what the application needs.
- OEM and ODM: branding customisation available.
- Dimensions and weight: the datasheet gives 136 x 60 x 37 mm and 359 g; a text edition of the catalogue lists 127 x 58 x 35 mm and 182 g, so the current revision is confirmed with the quotation.

Shipping & compliance
- Lithium battery: UN38.3 test summary and SDS are available for transport.
- Type approval, FCC or CE documents depend on the model and band version; confirm at quotation.
- Project pricing on request. MOQ and lead time depend on the model and configuration.
- Warranty and spare-parts terms are confirmed in the project quotation.
Typical applications
- Teams operating on licensed UHF channels within 400-470 MHz
- Sites that need a fixed, small channel plan of up to 16 channels
- Deployments that require narrowband 12.5 kHz or wide 25 kHz channel spacing
- Long shifts away from a charging point, where the documented 66-hour battery rating matters
- Adding units to an existing 400-470 MHz FM channel plan where the signalling matches
- Work-group traffic that suits one-frequency or different-frequency simplex operation
Frequently asked questions
Click a question to see the answer
Is this a vehicle-mounted radio?
The published data for this model documents a battery-powered unit with a 7.4 V working voltage, a 66-hour battery rating and a belt clip among the supplied parts, and it does not describe a dashboard mounting kit. The source catalogue groups the model in its mobile radio section, which is why it is published here, but our copy follows the datasheet. Tell us your application and we will confirm which mounting and power accessories the current revision supports.
What power supply does it use?
The documented working voltage is DC 7.4 V (+20%), supplied from the battery pack included in the packing list, with an adapter and charger for recharging. The average working time of the battery is documented at 66 hours; spare batteries can be included if the duty cycle calls for it.
Which band version should I order?
The documented frequency range is UHF 400-470 MHz. Band allocations and permitted power differ from market to market, so confirm the version against the licence you hold; if your assignment lies in another band, ask us before ordering rather than assuming this model covers it.
Do we need a licence to use it?
In most countries, transmitting on business radio channels requires a licence issued to the user. Licensing is the responsibility of the importer or the operating company locally; we provide the technical documentation needed for the application, including the published modulation and channel spacing figures.
Can it talk to our existing handhelds?
This is an FM radio documented at 400-470 MHz with 16 channels and 12.5 kHz or 25 kHz spacing. Radios already working on the same band and channel plan can share traffic where the signalling and spacing match; send us the channel plan and the models in use and we will check compatibility before you order.
The catalogue text and the datasheet show different dimensions - which is correct?
The published datasheet gives 136 x 60 x 37 mm and 359 g, while a text edition of the catalogue lists a smaller figure of 127 x 58 x 35 mm and 182 g. Because the two disagree, we publish the datasheet figures and confirm the current revision with the quotation; if the installed size is critical for your application, tell us and we will verify it in writing.
