The Victron Outdoor 4G GSM Antenna (VIC-GSM900100400) is designed to improve mobile signal reception for Victron GX LTE 4G systems in installations where the included indoor antenna is not enough. Optimized for 4G frequency bands, this outdoor antenna helps deliver more reliable connectivity for remote monitoring and system communications, especially in marine, RV, off-grid, and industrial environments.
Built for external mounting, this antenna uses a screw-mount design and includes a 3.0 m RG-316 cable with an SMA male straight connector, making it straightforward to connect to compatible Victron hardware. While tuned for stronger 4G performance, it can also be used across 2G, 3G, and 4G bands, giving installers flexibility in areas with mixed network coverage.
This is an ideal upgrade for installations where equipment is housed inside metal enclosures, utility spaces, engine rooms, or other signal-challenging locations. By moving the antenna outdoors, users can often achieve a more stable connection to the cellular network and improve the reliability of VRM remote access when paired with a compatible GX LTE 4G device.

Compatibility & Fitment
The Victron Outdoor 4G GSM Antenna is intended for use with the Victron GX LTE 4G and connects to the device’s LTE antenna connector, which is specified as SMA female on the GX LTE 4G. This makes the included SMA male straight connector the correct physical match.
It is best suited for installations where the GX LTE 4G is used for remote internet connectivity for a Victron GX monitoring system. Victron states the GX LTE 4G can be used with any GX device, provided the GX device is running Venus OS v2.60 or newer.
Works with:
- Victron GX LTE 4G cellular communication units
- Victron GX-based monitoring installations requiring stronger external LTE signal performance
Fitment notes:
- Connects to the LTE antenna port on compatible Victron GX LTE 4G hardware
- Suitable for marine vessels, RVs, cabins, service vehicles, and off-grid sites where outdoor placement improves reception
- Designed for fixed outdoor mounting via screw mount
- 3 m cable should be considered when planning routing and mounting position
Installation Notes
- Mount the antenna in a location with the clearest possible exposure for better cellular reception.
- Route the cable carefully to avoid sharp bends or abrasion.
- Confirm connector compatibility before installation.
- For best results, place the antenna away from major sources of interference and heavy shielding materials.
Maintenance Tips
- Periodically inspect the antenna mount to ensure it remains secure.
- Check the cable for wear, chafing, or UV/weather damage in exposed installations.
- Keep connector points clean and dry during service.
- Reassess antenna placement if signal strength drops after equipment changes or relocation.
Engineered for marine-grade reliability — because connectivity shouldn't stop at the dock.
