V-Dipole Hub for CB Mirror Mount

This hub can be used to build a rigid V dipole using a CB mirror mount and two 17 foot telescoping whips. The antenna can be adjusted to operate from 20 meters through 2 meters.

I modified this design from the hub used with my Savvy Yagi:

There are two hub versions:

• Skinny hub for the narrower CB mirror mount

• Fat hub for the wider CB mirror mount

The coupling nuts used with the two mirror mounts are different sizes, so make sure you print the correct hub for your mount.

Both hub versions can use either 3/8"-24 or M10 heat-set inserts. Most standard antenna whips use 3/8"-24 threads, while many of the cheaper Chinese whips use M10 threads.

You can also use the 3/8"-24 inserts with 3/8"-24 to M10 adapters if you want to use the less expensive M10 whips.
