GeoTool manufactures antenna mounts that install into the stake pocket holes found in the sidewalls of the bed of Pickup Trucks sold in the United States.  Our antennas use SO-239, NMO, 3/8"-24, and special insulators for use with antenna couplers, and other mobile, marine and land based antenna systems.  We have been in business since 1987.  We are expanding to include safety warning flags and 'buggy-whips'  to our list of supported equipment. We serve the commercial and amateur radio communication industries, as well as the mine safety equipment and off road safety equipment industries.
