rosin core solder to both wires and wait for the solder to cool.
cap and the wires. Repeat the same steps on the other side of the antenna. It is a good idea to verify continuity of your connections with a VOM (volt ohm meter) or a DMM (digital multimeter) before applying
heat to shrink the tubing. Good quality electrical tape can be used instead of the shrink tubing as well as liquid tape (available at Home Depot) or silicone sealant.
When the antenna is tuned for the operating frequency or frequencies, then you crimp both ferrules at the ends.The center insulator ferrules can be crimped after the previous steps are completed.
