SEUIC (Dongji) / UHF RFID external antennas
NA-7C165: UHF RFID external antennas
SEUIC (Dongji) NA-7C165 is a compact circularly polarized UHF RFID external antenna for fixed access-control, warehouse, logistics, retail and transport read zones. The exact model evidence lists region-specific gain, IP65 protection and pole-clamp mounting; reader pairing, feeder loss, tag mix and the installed read zone require validation.

UROVO is the primary established product resource, with SEUIC (Dongji) and selected platforms used where the capture method, form factor or deployment requirement needs another option. Published models follow an evidence, regional-configuration and RuggedLayer validation path.
Suggested profiles
- Compact access-control and doorway read zones
- Warehouse, logistics and transport portals with limited mounting space
- Retail or asset-tracking installations that need a smaller external antenna
Browse by device capability
- A compact external-antenna format supports a defined fixed UHF RFID read zone where installation space is limited.
- The region-specific gain, circular polarization and 72-by-78-degree beamwidth are model-specific manufacturer references.
- IP65 protection and a pole clamp support practical industrial mounting when the complete installation is protected appropriately.
- The antenna must be paired with a compatible reader, feeder and regional RF plan; it is not a standalone RFID reader.

A clear handoff at every layer
Five service layers for a more predictable device program.
RuggedLayer organizes access to multiple manufacturers into a consistent engagement model. Each layer has a defined input, deliverable and evidence boundary.
Service layers
- Select the permitted US or EU frequency configuration, apply the correct regional gain boundary, and confirm reader output, feeder cable and connector sealing before quotation.
- Set antenna height, angle, spacing, shielding and cable route around the target tag orientation and the required read boundary.
- Confirm the pole diameter, mechanical load, grounding, weather exposure and destination installation requirements with the site owner.
Deployment accessories
- Pair the antenna with the approved UHF RFID reader, one of the listed feeder cable options and the required N-type mating hardware.
- Scope pole clamps, brackets, weather sealing, cable protection, grounding and service access for the installed antenna position.
RuggedLayer Test Lab
Define a useful test, not a vague benchmark.
Tell us the labels, tags, application and operating conditions that matter.
- 01
Measure reads, missed reads, duplicate events and stray reads with the target reader, tags, feeder length, mounting angle and portal geometry.
- 02
Verify the regional RF profile, reader power, polarization, connector torque, cable loss, ingress protection and recovery after power or network interruption.
- 03
Freeze the exact antenna, reader, cable, mounting, tag population, RF settings and acceptance thresholds before a production rollout.
