UX-240P patch GPS antenna

The UX-240P GPS patch antenna is an external accessory designed by ICOM to receive Global Positioning System (GPS) signals. It is specifically intended for use with compatible marine equipment, such as certain ICOM marine VHF radios 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 GPS (Global Positioning System) signals on the L1 frequency (1575.42 MHz). It enables 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 any additional external power source.

Yes, the UX-240P GPS patch antenna is designed to be compact. Its small size makes it easy to discreetly integrate on various types of boats, even in confined 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. It is the ICOM device, once it has received the GPS data, that 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 connected ICOM device. It is this ICOM device, if compatible, that will process the GPS data and may convert it into NMEA 0183 or NMEA 2000 messages to share with other onboard navigation equipment.

The UX-240P antenna is primarily intended for use with ICOM marine VHF radios featuring an integrated GPS receiver. Although 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 GPS patch antenna is supplied with a 5-metre coaxial cable. This length is usually sufficient for most onboard installations on a sailboat.

For optimal performance, the UX-240P GPS antenna must be installed in a clear location 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 cable of the UX-240P antenna by using coaxial extensions compatible with SMA connectors. However, each extension and connector introduces a signal loss, which may affect the antenna's performance. It is recommended to limit the total cable length to the bare minimum to maintain optimal GPS reception.

Installing the UX-240P antenna is generally straightforward. It involves selecting a suitable location, securing the antenna (with 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. Also ensure the cable is routed to avoid pinching or damage, and that the SMA connector is tightly secured to guarantee waterproofing and signal quality.

It is strongly advised against painting the UX-240P patch GPS antenna. Paint, especially if it contains metal particles, could interfere with the antenna’s ability to correctly receive GPS signals, thereby reducing its performance or rendering it inoperative.
