Antennas

Keep an eye on your course, data, and safety

Navigation and communication are crucial for safety and situational awareness. Interfaces like NMEA 2000/0183, suitable sensors, and correct voltage are critical.

Many systems can be expanded step-by-step – from a simple display to a fully networked setup.

This way, you get technology that truly supports you and performs well at sea.

Discover variants, materials, and designs built for marine use. This ensures you find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

Can I use one antenna for both VHF radio and AIS simultaneously?
With an AIS splitter, this is possible – it separates the signals so that the radio and AIS receiver can use the same antenna without interfering with each other. Without a splitter, you should plan for a separate antenna for AIS.
How does cable length affect reception?
Coaxial cable attenuates the signal – the longer the cable, the more loss. For long distances, you need low-impedance cable with low attenuation. As a rule of thumb: it's better to invest a little more in the cable than to skimp on antenna height.
What does the dB value mean for VHF antennas?
The dB value describes the antenna gain. Higher values mean more range horizontally, but also a narrower radiation pattern. On a sailboat that rolls and pitches, an antenna with lower gain can therefore be more reliable in everyday use than one with a very high dB value.
What is the most common connector type for marine antennas?
PL-259 is the standard for VHF marine antennas and fits SO-239 jacks, which most marine radios have. GPS antennas, however, often use BNC or TNC connectors – this information can be found in the respective device's manual.
