[time-nuts] GN-GGB0710 GPS Antenna Mounting Thread

[Bob kb8tq]

Hi

Indeed this is exactly what is done with a pipe thread. It’s not designed to be fiddled 
with a lot. You put it together and that’s it forever and ever. Some bright engineer 
might have decided that antenna mounts fit in the same category. 

My bet still would be on a tool or die that was a bit past it’s “back to the shop for a 
touch up” point though.
