Releasable magnetic antenna mount with anti-rotation feature

An assembly to connect a mast to an off-road vehicle, the assembly comprising:

• a mount assembly comprising:
• a casing being cylindrical, hollow, formed from non-magnetic materials, closed at its proximal end except for a circular opening, and open at its distal end;
• and
• a bolt, formed from ferromagnetic material, that passes through said circular opening of said casing to secure said mount assembly to said off-road vehicle;
• and
• a base assembly comprising:
• a cylinder formed from non-magnetic materials and of a diameter less than the inner diameter of said casing with a first cavity at its proximal end and a second cavity at its distal end, and a channel connecting said first and second cavities;
• a magnet sized to fit into said first cavity and having a passage in its center;
• an adapter sized to fit into said second cavity having a tapped hole in its proximal end and an opening to receive the mast at its distal end;
• and
• a screw that passes through said passage and said channel to mate with said tapped hole in said adapter;
• the proximal end of said base assembly insertable into distal end of said mount assembly to releasably couple the two assemblies by a magnetic connection between said magnet and said bolt;
• wherein a head of the screw is configured with a size and shape adapted to fit within a recess formed in a head of said bolt, preventing rotation of the base assembly thereby.
