Anyone know how one gets on the above newsgroup?? Now one has been able to provide me with an answer to my question concerning an external antenna for a tripmate. I'll to dig it out from the newsgroup since I was told by a person at Delorme that it has been done. Thanks MS

Here is part of an article on the TripMate:

6) Delorme TripMate GPS Receiver: This $150 receiver is a 12 channel receiver but it has no display. It cannot use an external antenna. It is "rain resistant" and so may be itself mounted on your car's roof. The TripMate GPS receiver is designed specifically to work with Delorme's Street Atlas 4.0 software and unless connected to a laptop with SA4 running, the TripMate shuts down and provides no data. This unit acquires quickly and maintains lock well. However, its lack of a stand alone display, and the fact that it only works with Delorme Mapping software products makes it less desirable than others. Speed capability is reported as 900 kph.

I think the best advise is to consider the TripMate an external antenna which has a builtin GPS. I've found my TripMate to be sufficiently water-resistant that I've had no problems, thought I don't leave it mounted full time, however. A 'GPS window' in the roof woudl be the ideal situation for a permanent installation--very low profile (perhaps a 1/4 inch tall), and done right--rather water resistant. I'm going to use an 8 by 10 inch piece of plexiglas probably behine the B pillar's roll bar.

Thanks,
