My GPS antenna currently feeds directly to my RDP148 (Navnet VX2 vintage), and then there is a cable with GPS data leaving the RDP and going to the DSC equipped VHF so the radio gets location info.
When anchored, I'd like to turn off the RDP as it draws so much power but I don't want to turn of the VHF. But if I do this, the VHF will complain about not knowing a position.
My son suggests we split the signal coming from the GPS antenna before it gets to the RDP148 and send one signal to the RDP and the other to the VHF. (We'd simply splice a "Y" into the GPS antenna cable.) I'm guessing we'd need to look at how to ensure the antenna gets powered if the RDP is off. But the bigger question is can a Furuno GPS antenna send a signal (sentences?) to two different devices at the same time. (I don't know if the signal requires a certain amount of power, and if it is being split to go in two directions at the same time if I'm somehow diminishing the strength of the system.)
Or... if there are other approaches to solve the problem I'm trying to fix, please feel free to suggest.
