As of late this month Lowrance LMS-337C DF GPS will be available as an
LMS-339C DF IGPS with internal antenna. It is recommended fro use on open
cockpit or center console boats.

For cost and ease of installation reasons I'd prefer to use an internal
antenna unit. Seems to me that it would make little to no difference in
satellite reception on my center console boat.

Do you agree?

Thanks,
Butch

Yes. And I would go the same route with my open cockpit runabout if I was
in the market for a GPS and if the unit was within my budget for a GPS.

Once upon a time (1999ish) I switched from an internal antenna to an external
antenna on my 17' Boston Whaler Montauk center console. Same GPS. The
signal strength bars were noticiably better with the external antenna. A couple
of years later I bought a new GPS. I spent a few extra bucks for the external
antenna version.

Maybe it was just that the external antenna was a better antenna. Maybe it was
the metal rail over the top of the windshield.

=====================================

An external antenna will almost certainly give you a stronger more
reliable signal assuming that it is mounted in the clear. That said,
you may very well be happy with the internal antenna. If you have a
handheld GPS with an internal antenna you could temporarily put it in
about the same place as you are proposing for the Lowrance and see how
it performs there.

My Garmin 162 has an internal antenna and has no problem getting fast and
consistent satellite locks with WAAS or without. If the only thing the
signal has to shoot through is a canvas bimini top, such as in my
installation, I wouldn't hesitate to go with an internal antenna. Sure
simplifies the installation.
