GP33 antenna diagnostic procedure


Furuno Super Fan
My GP 33 has ceased to see the satellites today. It has the same behavior with or without the antenna cable connected or not. Are there any readings that can be taken on the connector (antenna side) that can provide a clue has if the antenna is ok (ohm reading or else ?)

Yes. You can check at the connector on the antenna cable for approximately 270 ohms between the center pin and the connector. Also, ensure that you have 5Vdc between the center and threads of the antenna connection of the GP33.
Thanks very much :respect i had i defective homemade connector (i had to extend the original wire by 3 feet). The diagnostic was very easy with the information provided !
