4G/5G Marine Network Antenna
Shore-network internet for near-coast operation, with VSAT fallback.
- Receives shore base-station signal and provides onboard internet
- Near-shore coverage up to roughly 35 nautical miles
- Works alongside VSAT with automatic priority switching
- Supports voice, video and fleet management traffic
Inside coastal coverage, the cheapest bandwidth a vessel can get is the shore mobile network. The marine 4G/5G antenna receives the base-station signal and converts it into an onboard internet connection, supporting the major Chinese carriers and, with the appropriate SIM and modem, local carriers elsewhere.
The documented working range is the near-shore band up to about 35 nautical miles, subject to carrier coverage. Within that band the link is high-bandwidth and low-cost compared with satellite, which makes it the natural default for fishing fleets, harbour craft and coastal ferries.
The important design point is that this antenna can run alongside a VSAT terminal rather than instead of one: the system is documented to work together with the vessel VSAT, switching priority automatically so the ship uses the cheaper shore link when it is available and falls back to satellite when it is not.

Buyer questions
4G/5G Marine
The two questions that come up most often on this platform. Anything else — write to sales@tvrovsatantenna.com.
Can it replace VSAT entirely?
Only inside coastal coverage. Beyond roughly 35 nautical miles you leave the shore network, which is why the documented configuration combines the 4G/5G antenna with VSAT and switches priority automatically.
What can the crew actually do with it?
The catalogue lists internet access, voice and video calling, CCTV backhaul, and fleet functions such as equipment maintenance management, voyage management and vessel tracking.
