Assembling the Receive Portable Flag Antenna
1. Assemble the transformer core using the following components:
Binocular Core, Teflon Tube, Green Magnet Wire and Red Magnet Wire.
The core is made into a transformer that uses the Green wire as the Secondary and the Red wire
as the Primary,
2. Using the core as a guide, cut the Teflon tube into 2 pieces the same length as the core.
3. Using the green magnet wire, insert one end into one of the Teflon tubes in the core allowing
approximately 1/2" hanging out. Make 12 turns through the Teflon tubes in the core. Keep the
wire snug. One turn is once through each side of the core.
Using the red magnet wire, insert one end into the core (not through the Teflon tubes)
allowing approximately 1/2" hanging out. Make 3 turns through the core.
Trim the wires so there is approximately 1/2" sticking out both sides of the core.

Take care not to nick or cut the wires.
