[Amps] Need some help on a project

[Will Matney]

All,

If anyone is interested, there's another one of these that just came up for sale. The guy shipped mine the day I e-mailed him I sent payment. He's jet fast on this. You'll need a GPS antenna (magnet mount will do) like Garmin, etc., and must be an amplified antenna that uses 5 Vdc. Also needed is a -48 Vdc power supply.

GPS Frequency Standard 5 PPB;

Best,
