I modified my Zorro radio by replacing the original antenna with an external one. However, the nut securing the connector is located inside the radio housing, making it very difficult to properly tighten or loosen when switching antennas.
To solve this, I attached a large plastic screw to the nut using heat-shrink tubing and secured it with glue. This makes installation and antenna swapping much easier.
