Seatalk/nmea from gps antenna

[BillBerner]

Hey there
Anybody know if I can split the feed to/from my Raymarine 125 gps antenna so that I send a seatalk feed to my c70 chartplotter and nmea directly to my icom 402 dsc VHF?
Goal is to have lat/Lon always fed to radio whether chartplotter is on or not

I know that the antenna/rcvr outputs both over the same wires, but I'm worrying about roasting it or the radio and/or the Instruments networked over sea talk

Thanks

Responding to my own question after experimenting.
No you cant split the feeds to get both simultaneously
