[TG] [TG11] GA 150 and Axiom PRO 9" MFD compatibility

[Tom - Raymarine - Moderator]

Hello Cocoloco,

An external GPS sounds like a good plan in your instance. The GA150 is a passive antenna which boosts the signal to the internal receiver in Axiom *Pro*, eS, a9 and a12 MFDs. It's not compatible with Axiom non-Pro. For a non-Pro Axiom, you'd use the RS150 active (NMEA2000/SeatalkNG) GPS receiver. Both Axiom Pro+GA150 and Axiom+RS150 combinations have essentially the same GPS performance, which is fantastic. You could use an RS150 with Axiom Pro: it would be a more expensive option than the GA150, but could be seen as adding a redundant backup into the system. Some people like that. There's no GPS in the Quantum radars (I think it could be hard to do that from an RF interference point of view: GPS signals are incredibly low-power and very sensitive to noise.)

Regards,
Tom
