How do you tune the Everhardt TSM-3 antenna?

1. Remove the cap from the antenna.
2. Then remove the foil around the antenna until you see the wire coil.
3. Carefully pull the thread out of the thread spool a little and then cut off a small piece and push the thread back into the spool.
4. Replace the cap on the antenna.
5. Measure the SWR, if it is still not correct, repeat the previous steps from 1 to 4 until your SWR is correct.
