GPS active (+25dB) antennas are available from Waters and Stanton (and 
probably others) for around Ł35.
You might find those Motorola chips already put 5v on the antenna line.

There are also surplus Garmin all-in-one antenna units around - 12v in, 
data out.
Some were on sale at the Telford rally for Ł5, I'm told.

Walter.
