I am looking into buying another Standard Horizon chart plotter (they are relatively cheap, can live in the cockpit unnoticed and provide all the information I need), but my two earlier units on two other boats had external antennas that mounted to the stern rail.

These newer units have "internal antennas" that (according to the sales people) can "punch" through a bimini. Has anyone had any good (or bad) luck with this type of installation? With the Standard Horizon, the external antenna is now an option with a $150 price tag ...a purchase that I would rather avoid if possible. Thanks!

All of my handheld GPSs work fine even down below. A bimini shouldn't be an issue.

Mine always work. I have found that sometime is takes a few minutes longer than normal to locate sufficient satellites but once they are found, it hasn't been a problem.

Unless your bimini is coated with metal foil the signals should get through with no attenuation. My hand held GPS works best under clear skies, it is a bit slower with heavy overcast and sometimes loses it satillites when down 2 floors in the house. It works well in my car with a steel roof and glass windows. I can try it next week in a metal tractor shed.

I have a Garmin

With internal antenna. It works fine under a bimini with solar panels on top. Never a problem, unless you consider it takes a couple extra minutes to lock on when powering up.

Thanks for the heads-up guys. Now feeling better about saving $150 ...the optional external antenna.

Re: I have a Garmin

Yeah, Garmins are quite expensive. Paid around $1000.00 for it at a marina store in New Jersey. I still have the receipt for it somewhere. Just sent off for the registration last week.

Well for an in expensive chart plotter can I recommend my setup?.... I am using a iPad with the Navionics
software downloaded from the app store. I keep the iPad in a 'Otterbox'.

The complete investment is about £600 and I have a device that performs many functions including all my weather, email, stores all my manuals in PDF format and gets me on this forum!

We have used the CP300i on two boats now, one with a substantial hardtop over the cockpit and it worked flawlessly. Chuck

I've got a Garmin GPSMap 540s flushmounted to the bulkhead in the cockpit, I'm only using the internal antenna. It shoots through the fiberglass deck and the bimini, and haven't had any problems getting a lock, even in the worst of weather...
