How do you tune an Everhardt TSM-4 antenna?

Important: You need a 550 cm coax cable for a good SWR adjustment. This coax cable is not included.

1. Remove the cap from the antenna
2. Then remove the foil on the antenna until the wire coil is visible
3. Carefully pull the thread out and cut a small piece and push it back
4. Replace the cover cap on the antenna
5. Now measure the SWR and repeat the previous steps until you have a good SWR
