Garmin has a ga 26 with a 6 ft lead and they also have one that hooks to the
windshield on the inside. You might want to look at their web site under
garmin gps III plus accessories.

what a great site... i was able to see all of the garmin additions. I think
just having an antenna that would be movable would work for me. I could put it
in the car, or the gm or or. Just my thoughts. thanks for the site info...
really looks good.

I see CRS got me again. The correct catalog page is 68 vice 62.

For those of us using the Garmin III Plus, the Garmin company sells a
extension of the antenna with a 6' lead so we can position it in another
location. Just my thoughts.

Paul,

I don't have the West Marine catalog here at work, but IIRC, there wasn't
anything listed in there that I liked. The Garmin GA28 low profile antenna
was the one I was planning to use. Sells for around $100. The only
downside that I can see is that it comes with 30 feet of cable. I'm no
radio engineer, but I would think that the cable could probably be shortened
since this is only a receiver, but I'd probably want an opinion from Garmin
before I got out the wire cutters.

Garmin also makes the GA29 mast mount, which is the same unit in slightly
different packaging that could be mounted to a roof rail, ladder or mirror
if for whatever reason you didn't want to come through the roof.

Paul,

The GA29 would resemble the truck antenna you refer to, but is much
smaller(about 3 inches in diameter). I believe the truck antenna also
contains the receiver and may contain some other comm equipment(I know that
many truck lines track their vehicles now and I believe it's all part of the
same system). The GA28 is just a "bump" about one inch high, two inches
wide and three inches long. There's a picture of it on the net somewhere -
I'll try to find it(for some reason, it ain't on Garmin's site :

The GA28 can be seen at:

The GA29 can be seen at:

Another possibility that I've considered is the "Tri-M Mighty Mouse"(honest,
I'm not making this up) that can be seen at:

http://www.thegpsstore.com/site/images/mm.jpg

It's not as pretty, but at $70, the price is right.

Al,

What I'm looking for is one that attaches permanently to the body and routes
the cable inside. They're no pictures of the accessories on their site, but
you can see the GA26 right under the GA28 at:

Al,

My wife always fusses about all the cables whenever we travel, so I'm trying
to clean things up a little. The "Mighty Mouse" I mentioned earlier is a
pretty good active antenna that uses a magnetic mount.

Check out:

http://www.gpscables.com/catalog.html

Paul Bartz, check out the "Skymaster" bulkhead mount antenna at the above
site. Looks like it's about 4 inches in diameter and about one inch high -
you'd never see it from the ground if it was mounted on the cab.

This site also has some good links at:

http://www.gpscables.com/links.htm

Joe Mehaffey's site at:

http://joe.mehaffey.com/

has lots of good info too.

Enjoy,
Patrick

Hi All!

I use a DeLorme GPS system and am considering mounting the receiver
(antenna) inside a roof vent cover. The wire would allow the vent to be
opened and closed normally, and no more holes through the roof. While
DeLorme doesn't offer any externally mounted antennas, they said that
any antenna using the NMEA0183 standard code would work with their
software. Additionally, if a longer cable is required, a NULL modem
cable with 9 pin connectors can be used. I think that DeLorme gives the
biggest GPS bang for the buck! I hope this helps somebody.

Hi Roy,

I was recently looking at DeLorme's web site and it appeared that they only
offered the GPS system with the city street mapping system _OR_ the highway
mapping system. Do you know if it is available with both mapping systems or
if you can use both????

Thanks,

The DeLorme GPS works just fine with either. Personally prefer Street Atlas 7.0
over the AAA program but the GPS couldn't care less.

Marion,

I agree with Melvin's reply. While I have both, I only use the Street
Atlas 7.0. I think it's the way to go.

Am I to understand that the Earthmate/SA7.0 for $199 which I just saw at
> delorme.com is a good reliable system for use on the road in a GMC?

Ken,

In my opinion, yes. For the money, I don't think the DeLorme can be
beat. This assumes that you already have a laptop with a CD-ROM drive.
Also, you may be able to find it for less than the retail price of the
web site.

Roy,

The Delorme Tripmate and Earthmate GPSs do not accept external
antennas. The Delorme software works with receivers(not antennas) using
the NMEA0183 code. If you want to use an external antenna, you'll need
to buy another GPS that has both a serial port outlet and a remote
antenna connection.

One other option is to mount the Delorme receiver to a suction cup style
radar detector windshield mount(especially if you have the smaller
Earthmate).

Also, if you're looking to buy Delorme products, check on eBay first.
They're usually available there. Just bid carefully.

Patrick,

Excellent point regarding the GPS antenna vs. receiver. Frankly. I
don't want, or need, an external antenna. My Delorme receiver works
just fine laying on the dash. If, however, I want to move it out of
sight, I would consider locating it inside of a roof vent cover.
