GPS Marine Antenna
Directional Marine Antenna is designed to receive the signal from GPS technology. Works in the 1575.42 MHz band. In combination with the integrated amplifier, this active antenna achieves up to 42 dBi of total gain. Thanks to IP67, this antenna is suitable for outdoor use. The antenna is highly resistant to harsh weather conditions. The antenna includes a 1 m long RG58 coaxial cable, which is terminated with an N (m) connector.
Connector specifications N:
Connectors with a screw-thread mechanism. N connectors are characterized by high reliability and mechanical stability. The characteristic impedance of the connector is 50 Ohm and the working frequency ranges up to 11 GHz. Temperature range is -65 °C to +165 °C. N connectors are used, for example, to connect wireless WLAN devices, satellite systems and GSM / GPS / Wi-Fi antennas.
Cable specifications RG58:
The RG58 coaxial cable is compatible with connectors applicable to a 5 mm cable diameter. It is mainly used for the 0-1 GHz frequency range, it can also be used for higher frequencies, but at the cost of higher attenuation. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The most common cables of this type have a temperature range of -20 to 75 ° C. This cable is suitable for external WiFi / GPS / GSM antennas. It is also often used for creating cable adaptors with connectors such as BNC / FAKRA / FME / N / SMA / TNC and others. There are also specially modified types of RG58 cables for outdoor use, which are UV resistant, as well as for use in extreme conditions. There are made of different materials, different qualities.
The antenna can be used for these GARMIN devices:
GPSMAP® 78/78s (with adaptor MCX to BNC 010-10121-00)
