The Garmin GPS 15H / 15L does NOT have an antenna built in. As Scott pointed out, the manual doesn't say what kind of antenna connector it has, but on the Garmin site under accessories, several antennas are listed. One I looked at had a BNC connector, but others including the GA 27C have an MCX connector. My assumption would be that the connector on the 15H / 15L is an MCX. The accessories also list a BNC to MCX adapter, so that seems to back up my assumption.

I think the GPS 15 is a bit cheaper, but it isn't WAAS capable like the GPS 15H / 15L.

The Garmin GPS18 PC & LVC are "hockey puck" style GPS receivers with the receiver and antenna all in one unit. Both have a magnetic base, but there is a threaded hole in the bottom if you want to bolt it in place. The PC version has a 2 M long "Y" type cable with a cig lighter plug on one leg with the 5V regulator built in, and a DB9 data connecter on the other. The LVC version has a much longer cable... 3 M I think. There is a header on the end of the cable that Garmin uses for testing, but you can just cut it off and solder the bare wires to your own connector or right onto a circuit board. You need 5 V for the LVC version. It's rated at 4 V to 5.5 V. The GPS18 is WAAS enabled and waterproof.
