Poynting Marine Antennas 4G/5G, Wi-Fi and GNSS for Boats,
Yachts and Vessels
Poynting marine antennas are rugged omnidirectional antennas built for 4G/5G, Wi-Fi and GNSS connectivity on boats, yachts and ships. They keep the connection going as the vessel changes heading and moves with the waves.

How to choose Poynting marine antennas
Gain alone does not decide the choice. The router's MIMO configuration, frequency bands, cable length, mounting height and the vessel's distance from shore must be considered together.
Small boat, coastal cruising. PUCK-2, PUCK-5 or OMNI-402-5G with a two-port router.
Yacht with a single 4×4 router. SWIRL-4 or MIMO-4: cellular, Wi-Fi and GNSS in one housing.
Dual-modem router, two carriers. SWIRL-8: 2 × 4×4 cellular, 4× Wi-Fi, GNSS.
Cruising further offshore. Narwhal OMNI-902/904/914: high-gain cellular up to 8 dBi.
Long cable runs. SWIRL-CPE or EPNT-4: the router sits in the antenna housing and only Ethernet runs inside.
Superyachts and commercial ships. RIPPLE-8/16 and WaveHunter: 2, 4 or 6 routers.

Correct installation on board
Height
The higher the antenna, the further the radio horizon; a mast or radar arch is preferred.
Away from radar
Mount outside the radar beam plane, at a suitable distance from other RF antennas and large metal structures.
Short cable or CPE
Coaxial loss grows over long runs; move the router closer to the antenna or choose a CPE model.
Port mapping
Connect the cellular, Wi-Fi and GNSS cables to the correct router inputs and use all MIMO ports.
Sealing
Protect connectors against salt water with sealing tape; an IP68–IP69K housing does not protect the connection points.
Lightning protection
Grounding and a lightning arrestor on every cable. More: Poynting lightning arrestor.
About Poynting marine antennas
Does a Poynting marine antenna improve boat internet?
Yes. Placing the antenna outside the vessel, in a clear and suitably high position, gives a stronger and more stable signal than the router's internal antennas inside the hull. Results depend on the distance to the shore base station, network load, frequency and router capabilities.
How do I choose a 2×2, 4×4 or 8-port antenna for a boat?
The antenna's MIMO configuration should match the router's cellular antenna ports: 2×2 for a two-port router, 4×4 for a four-port router. 8-port antennas are for dual-modem routers or two routers; each modem runs 4×4.
Is higher antenna gain always better on vessels?
No. High-gain omnidirectional antennas have a narrower vertical beamwidth. If the base station falls outside this narrow beam as the boat rolls and pitches, connection stability drops. Gain should be considered together with vessel motion, mounting height and distance from shore.
Does a marine antenna provide internet offshore?
A marine antenna receives the existing 4G/5G signal better, but it cannot create a connection where there is no terrestrial network. As you move away from shore, the connection weakens depending on base station coverage and frequency band. Voyages beyond coverage require a satellite connection.
Where should a marine antenna be mounted on a boat?
As high and clear as possible, at a suitable distance from radar, metal obstructions and other RF antennas. Large metal structures can distort the radiation pattern. The mounting position should be chosen together with the antenna's manual, the superstructure layout and the cable route.
Does marine antenna cable length affect performance?
Yes. Coaxial cable loss increases with length and frequency. Cables should be short and low-loss. CPE solutions, with the router in the antenna housing, eliminate this loss by using an Ethernet cable instead of a long RF cable.
Are Poynting marine antennas compatible with every 4G/5G router?
Check the router's supported bands, number of cellular ports, MIMO configuration and connector type. Even when the bands match, a wrong MIMO pairing or unsuitable adapters and cables will limit performance.
