The APRS Skytracker comes pre-assembled with solar panels, Supercap and antenna wires attached. It is ready to fly out of the box with fishing line and tape included. The WSPR version comes with spools of magnet wire taped to fishing line but you will have to measure and cut the antenna wires to length and there is some soldering involved to attach the antenna wires.
