The Delorme Earthmate Consumer Grade Antenna works very well with Geographic Tracker (The latest version) The price was right $179.00 which included Delorme's TopoUsa and StreetAtlas. It is a simple USB connection with a suction cup mount antenna, I taped mine down (it was on a boat.) The antenna has about twelve feet of cable. The trick to getting it to work with Geographic Tracker is to have the Antenna hooked up first and the Delorme GPS interface software running before you start Mapinfo and Geographic Tracker. After that it is very simple to draw lines or points in your editable layer. One other thing, it is very important to have the projection of all of your layers set to WGS84. Beyond that, it is almost a no-brainer. Hope this Helps.
