LTE GNSS Antenna for T-Box Integration | V1398-004-A-01

The VLG V1398-004-A-01 antenna is an LTE and GNSS integration option for vehicle T-boxes and telematics terminals. Its narrow 100 × 30 × 14 mm package supports adhesive mounting in a sheltered location. For a T-Box antenna, the important starting point is the host’s antenna-port map: cellular feeds, GNSS input and any required diversity connections.

Key specifications and selection criteria

Define the cellular antenna connections

The listed cellular coverage is 824–960 MHz and 1710–2690 MHz. Compare these ranges with the T-box modem and intended networks. The TB-2377 promotional name refers to a combined assembly; obtain the connector and feed drawing to establish exactly how the supplied version maps to the modem ports.

Power the active GNSS path correctly

The positioning section lists GPS L1/BeiDou B1, RHCP and a nominal 28 ± 3 dB LNA. It requires 3.0–5.0 V, with a listed operating current of 10 ± 3 mA at 3.3 V. Confirm bias voltage and receiver input limits before connecting the antenna.

Use the available space without compromising reception

A narrow housing can fit locations that a wider assembly cannot, but mechanical fit is only one part of the decision. Keep the selected position clear of significant metal obstruction and test the complete vehicle or terminal arrangement. Review the 2.5 m cable routing, connector loads and adhesive surface preparation.

Validate the operating configuration

Check GNSS reception while the cellular modem transmits and the T-box power converters are active. Compare data connectivity at the target bands, and retain the tested hardware configuration for production. The enclosure’s IP52 rating is a reason to plan a suitable interior location.

Frequently asked questions

Does this T-box antenna cover every 5G band?

The listed cellular ranges do not establish full sub-6 GHz 5G coverage. Use the actual modem band requirements to select the antenna.

What should an OEM send for an integration review?

Provide the modem and GNSS receiver models, antenna-port map, housing drawing, cable requirements and intended installation location.
