Bend a loop in one end of each of the remaining wires to fit on the bolts. Put a bolt from the bottom up into one hole on the connector and slide on one washer. Slide on one of the wire followed by another washer then put a nut on top and tighten. Repeat for the other 3 holes.
Once the wire are attached as shown, bend the 4 wires downward about 45 degrees.
Now you’re ready to build the mast. This will be a piece of ¾ PVC of any convenient length. Mine is about 5 feet long.
The antenna in the pictures has served me for many years now. It has fall over while on a 30 foot mast. The mast was damaged by the antenna was not. It spends much of its life behind the seat in my truck where it gets bent and banged. I did originally solder the 4 radial wires on the connector but that proved to be a weak point. The radials keep breaking off so I went to bolts and have not had one break since. Maybe it was just bad soldering but bolts work for me.
