Reach RS3 UHF antenna 410-470 MHz

Reach RS3 UHF Antenna brings existing UHF correction infrastructure to Reach RS3 surveying workflows, enabling field teams to receive RTK corrections from compatible third-party base stations without changing their base station setup.

• Use existing UHF correction networks: Receive RTK corrections from compatible third-party base stations without requiring a secondary NTRIP connection.
• Activate the RS3 UHF radio: The antenna is required for workflows using the Reach RS3's built-in UHF correction input.
• Integrate with legacy survey infrastructure: TRIMTALK 450S compatibility supports teams working alongside existing Trimble, Topcon, and other compatible UHF base station systems.
• Work across demanding field environments: UHF correction reception supports surveying, mining, infrastructure, and construction workflows where existing base station networks are already deployed.

Overview and Who It's For

The Reach RS3 UHF Antenna connects to the dedicated UHF antenna port on the Emlid Reach RS3 and enables its built-in UHF radio to receive RTK correction data from third-party base stations using the TRIMTALK 450S protocol. The RS3 UHF radio is receive-only, and configuration is handled in the Emlid Flow app by matching the rover frequency and bandwidth to the base station's broadcast settings.

• Surveying and mapping teams: Work alongside existing TRIMTALK 450S-compatible UHF base station networks or mixed Emlid and legacy equipment fleets.
• Mining teams: Receive corrections from established UHF survey base station infrastructure without relying on cellular connectivity.
• Infrastructure and construction teams: Integrate the Reach RS3 into sites where UHF base stations are already the standard correction delivery method.

FAQs

Will this antenna work with the RS2+ or RS2?
No. The UHF radio is exclusive to the Reach RS3. This antenna has no function on the RS2+, RS2, RS+, or any other Emlid receiver.

What base stations are compatible?
Any base station transmitting RTK corrections in RTCM3 format over the TRIMTALK 450S protocol in the 410-470 MHz band, including Trimble base stations and other legacy UHF systems supporting the TRIMTALK 450S standard. Confirm compatibility with your base station documentation or site manager before purchasing.

Can the RS3 transmit corrections over UHF?
No. The RS3's UHF radio is receive-only. For base-to-rover correction transmission without cellular coverage, the RS3's built-in LoRa radio (868/915 MHz, up to 8 km) is the correct tool.

How do I configure the UHF link?
Open the Emlid Flow app, connect to the RS3, and navigate to Correction input. Set the frequency and bandwidth in the UHF cell to match your base station. Data rate is automatic based on bandwidth: 9600 bit/s at 25 kHz or 4800 bit/s at 12.5 kHz.

Do I need a radio licence to use this antenna?
The RS3 is receive-only and does not require a transmit licence. However, the base station transmitter operating in the 400 MHz band may require an ISED licence in Canada. Confirm with your base station operator before deployment.
