Socalgmrs I had not really considered that as I have the coax hanging vertically from the above the radio in a fixed location. However, you make a good point, so version 2 is designed to prevent lateral torques while still allowing the collar to be used as a wrench for the SMA nut. Also has the benefit of no glue and is similar to adapters that I have made for other SMA mobile antennas (i.e. Retevis RHD-771) .
