Telescopic antenna - mount sizes

Post by KX4QC »

Telescopic antennas - particularly for QRP - often end in male M10 threads.
Here's just one 18' example from Amazon:

And here is a common mount for portable / mobile antennas. Great but they all seem to have a 3/8" thread.

My kludge of a solution is use this adapter:

The antenna, mount are sturdy, but this adapter has short threads and is made of aluminum alloy. Maybe not so strong?

This works, but what's a better idea?

Amazon ASIN numbers are with each photo.
