Summary

Made this for a 1/4th wave ground plane antenna for GMRS. Realized that one could use this mount for any 1/4th wave ground plane antenna. You might have to bend the radials or modify the so-239 mount to clear the radials.

The mount uses one M6 and two M3 screws to attach it to the pole mounts or camera tripod mount. You most likely will need a longer screw to attach it to a tripod. Four M3 screws, four M3 washers, and four M3 locknuts is the hardware I chose to use to attach the so-239 to the bottom mount.

Used three different sizes of EMT conduit. 1/2, 3/4, and 1 inch. Used nominal sizes of the outer diameter of the pipes for creating the mounts. Zipties and or U-Bolts would attach the mounts to the poles.
