GPS-patchantenn UX-240P

The UX-240P GPS patch antenna is an external accessory designed by ICOM to receive signals from the Global Positioning System (GPS). It is specifically intended for use with compatible marine equipment, such as certain ICOM marine VHFs with an integrated GPS receiver.

Its primary function is to provide accurate GPS positioning data to compatible ICOM devices, enabling them to determine your location, speed, and heading for navigation or safety features such as DSC (Digital Selective Calling).

The UX-240P antenna is designed to receive signals from the GPS (Global Positioning System) system on the L1 frequency (1575.42 MHz). It allows your equipment to receive the positioning data required for navigation.

No, the UX-240P GPS patch antenna is an active antenna powered directly by the ICOM device it is connected to. It does not require an additional external power source.

Yes, the UX-240P GPS patch antenna is designed to be compact. Its small size makes it easy to integrate discreetly on different types of boats, even in tight spaces.

The UX-240P GPS patch antenna is equipped with an SMA male connector. This standard connector ensures a reliable connection with compatible ICOM devices.

The UX-240P antenna is designed to provide GPS data to a GPS receiver integrated in an ICOM device (such as a VHF). It does not connect directly to a chartplotter or multifunction display to supply raw data. The ICOM device, once it has received the GPS data, can retransmit it via NMEA 0183 or NMEA 2000 to other compatible navigation equipment.

The UX-240P antenna itself is not directly compatible with NMEA 0183 or NMEA 2000 protocols. It receives GPS signals and sends them as raw data to the ICOM device it is connected to. It is this ICOM device, if compatible, that will process these GPS data and may convert them into NMEA 0183 or NMEA 2000 messages to share with other navigation equipment on board.

The UX-240P antenna is primarily intended for use with ICOM marine VHF units featuring an integrated GPS receiver. While it is a standard GPS antenna, its use with dedicated GPS receivers from other brands is not officially supported, and compatibility in terms of connector, power supply, and performance cannot be guaranteed.

The UX-240P patch GPS antenna is supplied with a 5-metre coaxial cable. This length is typically sufficient for most onboard installations.

For optimal performance, the UX-240P GPS antenna must be installed in a clear area with a direct 360-degree view of the sky, free from obstructions by metal structures, masts, sails, or other electronic equipment that could block or interfere with GPS signals. Ideally, it should be mounted horizontally.

It is technically possible to extend the UX-240P antenna cable using coaxial extensions compatible with SMA connectors. However, each extension and connector introduces signal loss, which can affect antenna performance. It is recommended to limit the total cable length to the bare minimum required to maintain optimal GPS reception.

Installing the UX-240P antenna is generally straightforward. It involves selecting a suitable location, securing the antenna (using adhesive or screws), and connecting its SMA cable to the external GPS input of your compatible ICOM device. No complex configuration is required for the antenna itself.

Yes, it is important to avoid installing the antenna near sources of electromagnetic interference (such as other transmitting antennas, radars, or electric motors) and to ensure it has a clear view of the sky. Make sure the cable is routed to avoid pinching or damage, and that the SMA connection is tight to ensure watertightness and signal quality.

Painting the UX-240P GPS patch antenna is strongly discouraged. Paint, especially if it contains metallic particles, could interfere with the antenna's ability to correctly receive GPS signals, thereby reducing its performance or rendering it inoperable.
