Any more designs to suit a Garmin 310 ???

Lee .....G6ZSG.....



Lee,

These are free-space antennas, intended for fitting with a length of
coax
terminated in the particular connector that mates with the connector
on
your
GPS rcvr. My Garmin GPS-III takes a BNC and I have my patch antenna
mounted
on my van's luggage rack; Eight feet of coax brings the signal inside.

Not too sure what i want, i`m a bit of a newb to GPS....just bought
it!!!...

Not familiar with the 310 -- are you looking for an add-on antenna
that
physically mounts to your 310? ... or does the 310 require a special
coupling technique (non-connector)?

Same as the 320,330 and 340 series

My external antennas are all non-specific to the brand and model of
consumer-grade GPS receivers (those using only the L1 signal). The
connection method varies among receivers.

If you are buying an antenna, here is Garmin's web link to the manual:
http://www.garmin.com/manuals/Street...nersManual.pdf

See page 26 for a mention of the GA27C antenna. Of course, it comes
with the cable end being the right connector (MCX) for your receiver.
Hunt in your manual if the pages don't match the one I found online.

If you are making your own antenna from plans I linked to, you will need
to also buy a type MCX connector for the cable end, as that is the
connector
type specified he
http://www.garmin.com/products/sp330/spec.html (which is the link from
page 26 in the manual.)

www.jameco.com sells MCX connectors, but if you google for "MCX connector"
(with the quotes) you will get not only sources for the connector but also
quite
a few third-party vendors with ready-built GPS antennas using that
connector.
You are apparently in a large group of Garmin users who want an external
antenna.

Thanks.
