Is it overkill to install GPS antenna's on both Raymarine
chartplotters?

I have an E-80 going into the nav station, connected to GPS antenna
and Radar.

I have a 2nd E-80 going into the helm

My PC and the two E-80's will be connected via a 8-port hub.

Any con's, or for that matter, any substantial pro's to installing a
2nd GPS antenna connected to the E-80 at the helm ??

(I already keep a handheld garmin on board, as both a backup, and when
I want to conserve battery power)

Thanks,
Dan

Only 3 GPS's on board? Do Garmin know about this? Are you the master of the
QM2 by any chance?
