The antenna connection is exactly what it seems. You can attach anything to it from a few inches of wire to a full scale dipole. The radio tuner is quite sensitive.

These things are usually sold for use in a car with a 12V power supply, which goes straight into a 5V regulator. I use mine with a spare unregulated wall wart that supplies about 16V off load and it's been fine. I would imagine there would be problems trying to use it with a 5V supply unless the regulator was bypassed.
