2 GPS, one antenna


Active Member
I'm adding a 2nd Lowrance HDS unit to the car. I'd like to run a single Point-1 antenna for both units. Will this cause any issues?
as stated above...its simply a matter of connecting the NEMA bus from one GPS to another.

the only down side would be having two antennas gives diversity in case there was a failure, or the antenna got damaged by a rock or tree branch or whatever.....you loose both GPS's.

having done this in the past...I discovered some functionality carries over between the two. for example, when dimming one, both dimmed.
