[TG] [TG11] Can I use GA150 GPS antenna with AIS700?

RE: [TG11] Can I use GA150 GPS antenna with AIS700?
Hello Mike,

Sorry that you've not received a reply before.

The GA150 is different from the AIS700's antenna, and they are not tested or approved to be interchangeable. When I say approved, I mean in several ways - compliance with IMO AIS regulations (AIS GPS receivers are required to comply with the RAIM standard for integrity monitoring), marine EMC compatibility regs, and suitable performance and reliability for warranty purposes. Passive GNSS antennas come in 3V and 5V types, and I do not have any information on whether the AIS700 or GA150 are 3V, 5V or compatible with both supply levels. The AIS700 outputs a 3V level as do the displays that GA150 is compatible with but the AIS700's predecessor, AIS650, is 5V and it may be that the AIS700 antenna is dual-voltage capable but the GA150 is 3V-only. Frequency band is another area of possible incompatibility: the GA150 is a multi-band GPS+GLONASS antenna, whereas I suspect that the AIS700's may be GPS-only. I don't have the answers to these questions because this is not a connection that was ever intended to be made.

In short, as a manufacturer we can't approve using a non-compliant antenna with an AIS transceiver, and I think that there's a fair chance that they're not fully compatible because of the AIS's RAIM requirement and supply voltages.

To answer your other question though, the GA150 does show a 'capacitive' resistance that starts in the hundreds of kilo-ohms and rises as the cap charges when I measure one here. Your exact reading will depend on your meter, but yours doesn't sound abnormal.
