Fitting external antenna |
|
|
Hello,
Thinking about a Navman icn 520 but have been told because my windscreen
is heated I need an external antenna. The one recommended is Haicom:
MMCX External Antenna and the question is does anyone know how these are
fitted? I understand the base is magnetic so do I need to drill a hole
in the roof to route the cable? Anyone have any experience or knowledge
of this?
TIA.

You don't have to drill a hole in the roof unless you really want to!!!
You can just put the magnetic base on the roof and the cable will go between
the seal and the door.
You could get an antenna that attaches to the one of the side windows on the
rear window by such means as a suction mount. A good place to look for
external antennas in www.gpsw.co.uk of www.globalpositioningsystems.co.uk .
You will be able to see images of external antennas which will help you to
visualise the set up.

Antennas like that are meant for temporary installations where you
stick the magnet-mount on your car roof and route the cable through a
window.
If you're going to the trouble of drilling holes in your car, you
should find an antenna designed for that style of permanent mounting.

That depends - you might not even need an external antenna.
My Mondeo has a heated windscreen but the heated area does not extend
all the way to the edge at the bottom so my GPS happily sits on a mount
attached to the bottom right corner on the screen. It works well there
while being easy to view and not getting in the way of my external view.

It does not have to be outside the car. It can go anywhere that it has a
good view of the sky. If you do want to run it outside you can run the
thin wire through the door seal so there is not need to drill holes.

Don't botter with all the messing about. As far as I can tell it uses Sirf
Xtrac, which is very out of date now.
Get a modern unit with Sirf Star III and you probably won't need an antenna
at all. |

Make quite sure you really do need an antenna. I've yet to see a *heated*
screen that blocks the GPS signals, not that that means there are none, but
going on the basis of "is it true or hearsay?"
What I have seen is french cars with various weird "solar" glass which block
them very nicely, e.g. the Renault Laguna I had on loan the other month.
Luckily for me, my smart antenna is on a wire and just went through the
passenger door gap ok.
If you need one, sure, Haicom will do fine. The tidiest fit is through the
front bulkhead somewhere where wiring is going anyway, through the engine bay
and out behind the front bumper.
Most bumpers stick out and are made of a sort of plastic that GPS sees through
so this is usually a pretty good solution. Front bumper is good because you're
generally moving forward so when the position updates, it is slightly ahead of
events, rather than lagging behind. Rear parcel shelf, as far back as it goes,
is another good place.

Thanks for the info, much appreciated.
John.
