Le marche di VHF, antennas, stereo

This section includes all marine communication and entertainment electronics: fixed and portable VHF antennas, waterproof radios and stereos, digital TV antennas, 4G/5G internet systems, coaxial cables, and installation accessories. When choosing, it is best to start with the type of device—transceiver, audio, or connectivity—and check compatibility with the onboard system.

How to choose VHF antennas, marine stereos and radios

VHF radios: fixed or portable

Fixed VHF radios are installed on the bridge, connected to an external antenna and the onboard power supply, ensuring greater transmission power. Portable versions — such as the Cobra Marine HH350 models or Plastimo radios — are battery-powered and useful as backups or on small boats: assess battery life and water resistance. Some models include an AIS receiver, such as the Raymarine AIS700 or Simrad RS40-B, adding the reception of nearby ship positions without separate devices.

VHF antennas: length and type

VHF antennas differ in length and gain. Shorter versions are suitable for sailboats where heeling is significant; longer ones increase range on motorboats. Glomex offers several stainless steel and fiberglass models — including Elba, Task and Black Swan — in various sizes. Scout and Banten cover more basic needs. For CB antennas, Scout offers specific models.

Coaxial cables and installation accessories

The coaxial cable directly affects antenna performance. Glomex's RG8X type is among the most sought-after, available in various lengths. To complete the installation, you need pipe or deck mounts — single or double-jointed in ABS — lightweight alloy extensions and splitters. The Glomex RA201 AM/FM/AIS splitter allows you to share the VHF antenna between the radio and the AIS receiver, reducing wiring.

Marine stereos and waterproof speakers

Marine stereos must withstand moisture, salt spray and vibrations: check the IP protection rating of the front panel. Fusion (Apollo and RA series) and Boss Marine cover most installations. Clarion completes the range for those looking for specific solutions. Waterproof speakers should be matched to the RMS power of the amplifier; some models include programmable LED lighting. Fusion and Boss Marine offer two-way units in various sizes.

Internet connectivity and digital TV antennas

4G/5G internet systems — such as Glomex weBBoat Plus 5G and weBBoat Link PRO — allow network access via a data SIM even far from the coast. Digital TV antennas pick up the DVB-T2 signal in the marina: check if the model includes a built-in amplifier and DAB support for digital radio. Glomex covers this range with models such as Ballade and the series with a built-in amplifier.

Domande frequenti

Qual è la differenza tra un VHF fisso e uno portatile per uso nautico?

Il VHF fisso è collegato all'antenna esterna e all'alimentazione di bordo, offrendo maggiore potenza e copertura. Il portatile funziona a batteria, è più versatile come soluzione di emergenza o per piccole barche, ma ha portata inferiore.

Come si sceglie la base giusta per un'antenna VHF?

Dipende dal punto di installazione: le basi per tubo si fissano a pulpiti o boma, quelle da coperta su superfici piane. Lo snodo singolo o doppio permette di orientare o abbassare l'antenna. Prima di scegliere, verificare il diametro del supporto e il tipo di filettatura dell'antenna.

Lo splitter AIS/VHF serve davvero o è meglio un'antenna dedicata?

Lo splitter permette di condividere un'unica antenna VHF tra la radio e il ricevitore AIS, riducendo i cablaggi. È una soluzione pratica su barche già equipaggiate; un'antenna dedicata al ricevitore AIS offre prestazioni leggermente superiori ma richiede installazione aggiuntiva.

Cosa verificare prima di installare uno stereo marino?

Controllare il grado di protezione IP del frontale, la tensione di alimentazione (il 12V è lo standard più diffuso in nautica), la compatibilità degli altoparlanti con la potenza RMS dell'unità e lo spazio disponibile nel piano plancia o nell'alloggiamento previsto.
