Detailed description

Dissenyada per a una recepció de senyal de posicionament òptima, l’antena Garmin GA™ 38 GPS i GLONASS negra és una solució externa que millora la precisió i la fiabilitat de la navegació a bord. Destinada específicament als sistemes Cortex® V1 i M1, així com a diversos traçadors de cartes, VHF i AIS Garmin compatibles, representa una actualització per als aparells amb l’antena interna obstruïda o per als que necessiten un rendiment GNSS superior.

Rendiment i compatibilitat

La GA 38 destaca pel suport de sistemes de doble constel·lació GPS i GLONASS, assegurant una adquisició de posició més ràpida i una millor precisió fins i tot en condicions difícils. Amb unes dimensions compactes de 91,6 mm de diàmetre per 49,5 mm d’alçada i un pes de 128 g per al model negre, s’integra discretament. El seu xassís d’aliatge plàstic d’alt impacte, totalment estanc segons la norma IEC 60529 IPX7, garanteix una resistència als entorns marins exigents, amb un rang de temperatura de funcionament de -30°C a 70°C. Es subministra amb un cable BNC-SMA de 10 metres, que permet una flexibilitat d’instal·lació.

Opcions d’instal·lació versàtils

L’antena Garmin GA 38 ofereix diverses opcions de muntatge per adaptar-se a diferents configuracions de vaixell. Pot instal·lar-se sobre una superfície plana mitjançant el suport de muntatge en superfície inclòs, o fixar-se sobre un pal estàndard de 1 polzada de diàmetre exterior amb una rosca de 14 fils per polzada, gràcies al suport de muntatge en pal subministrat. Aquestes opcions permeten posicionar l’antena de manera que tingui una vista lliure del cel, evitant obstruccions per la superestructura, el radom o el pal, i minimitzant les interferències electromagnètiques provinents del motor, el radar o les ràdios VHF. A diferència del model blanc, el suport de muntatge sota la coberta no s’inclou amb la versió negra.

« GA 38 antenna: the strategic choice for reliable GNSS positioning aboard »

The Garmin GA 38 antenna is a critical component for navigation and communication systems requiring precise and continuous GNSS positioning. Its ability to simultaneously process GPS and GLONASS signals provides a significant technical advantage over single-constellation GPS antennas, offering redundancy and improved accuracy—especially in areas where visibility of a single constellation may be limited. For a sailboat with a high mast or a powerboat with metal superstructures, an external antenna like the GA 38 is often essential to ensure reliable positioning data, which is crucial for AIS systems or VHF Digital Selective Calling (DSC) functions.

Installation of the GA 38 is simplified by its versatile mounting options (surface and mast), allowing integration on various types of boats. It is critical to maintain safe distances from electromagnetic interference sources (engine, radar, VHF antennas) and ferrous objects to optimize signal reception and prevent compass deviation. While mounting below deck is mentioned, it is important to note that this option is limited to fiberglass surfaces, and the specific mounting bracket is not included with this black model. The GA 38 integrates seamlessly into the Garmin ecosystem, providing a reliable solution for Cortex V1/M1 users and other compatible equipment seeking to maximize GNSS performance without the complexity of more advanced antenna systems.

The Garmin GA 38 antenna is specifically designed for Cortex® V1 and M1 systems. It is also compatible with various Garmin chartplotters, VHFs, and AIS units that feature an ANTENNA or EXT GPS port with a BNC connector.

What type of connector does the GA 38 antenna use to connect to Garmin devices?

The Garmin GA 38 antenna uses a BNC connector to connect to the port labeled ANTENNA or EXT GPS on a compatible Garmin chartplotter.

What mounting options are available for the Garmin GA 38 antenna?

The Garmin GA 38 antenna offers several mounting options:

Mounting on a flat surface.Mounting on a standard 1-inch diameter mast with 14 threads per inch (mast not included).Under-deck mounting is not provided with the black models of the antenna.

What are the important considerations for choosing the mounting location of the GA 38 antenna?

For optimal performance, the antenna must be mounted in a location with an unobstructed view of the sky in all directions. It is recommended to avoid shaded areas caused by the boat's superstructure, a radome, the mast, or near the engine and other sources of electromagnetic interference (EMI). It should also not be mounted near ferrous metal objects or directly in the path of a radar.

Can the GA 38 antenna be installed under the deck?

The under-deck mounting kit is supplied only with the white antenna models. Therefore, this option is not applicable to the Garmin GA 38 black antenna.

How to mount the GA 38 antenna on a flat surface?

To mount the antenna on a flat surface:

Use the surface-mount bracket as a template to mark the three pilot-hole locations and trace the cable hole in the center.Drill the three pilot holes with a 3.2 mm (1/8 in) bit.Drill or cut the central cable hole with a 25 mm (1 in) bit or hole saw.Attach the surface-mount bracket using the included M4 screws.Run the cable through the center hole and connect it to the antenna.Ensure the large gasket is seated on the underside of the antenna, place the antenna on the bracket, and turn it clockwise to lock it in place.Secure the antenna to the mounting bracket with the M3 adjustment screw and a 1.5 mm hex key.

How to mount the GA 38 antenna on a mast?

To mount the antenna on a mast (not included, 1 inch OD, 14 threads per inch):

With the cable routed outside the mast: Pass the cable through the mast mount adapter and place it in the vertical slot. Screw the adapter onto the mast, connect the cable to the antenna, then place the antenna on the adapter and turn it to lock it in place. Secure with the M3 adjustment screw.With the cable routed through the mast: Drill a 19 mm (3/4 in) hole in the mast for the cable. Secure the mast to the boat. Screw the mount adapter onto the mast. Route the cable through the mast and connect it to the antenna. Place the antenna on the adapter and turn it to lock it in place. Secure with the M3 adjustment screw.In both cases, ensure you test the location before final installation and route the cable away from sources of electronic interference.

What precautions should be taken when drilling for the installation of the GA 38 antenna?

When drilling or cutting, always check what is on the other side of the surface to avoid damaging the vessel. If drilling into fiberglass, use a countersink bit to drill a pilot hole only through the top gelcoat layer. This helps prevent cracking of the gelcoat when screws are tightened.

Is it necessary to test the mounting location before permanently fixing the antenna?

Yes, it is strongly recommended to temporarily test the antenna at the chosen mounting location to verify its proper operation. If interference with other electronic devices is detected, the antenna must be moved and retested until a full or acceptable signal strength is observed before permanent installation.

Should the GA 38 antenna be mounted away from other electronic equipment?

Yes, the antenna must not be mounted near the engine or other sources of electromagnetic interference (EMI). Additionally, it must not be mounted less than 1 metre (3 feet) from a VHF radio antenna or the path of a radar to avoid interference.

What is the safe distance from a compass for the GA 38 antenna?

The safe distance from a compass for the Garmin GA 38 antenna is 114 mm (4.5 inches).

What is the warranty policy for the Garmin GA 38 antenna?

The Garmin GA 38 accessory is covered by Garmin's standard limited warranty. For detailed information, it is recommended to consult Garmin's support section on their website.
