    NSTALLING THE NTENNA After a site has been selected, install the antenna as follows: 1. Verify that the thread on the mount does not extend more than 7/8" (22 mm) to ensure the antenna receptacle is not damaged when the mount is inserted. If it extends further than 7/8" (22 mm), add two jam nuts to shorten the exposed thread, ensuring the nuts are well tightened.

    NTENNA The GNSS-750 is designed to withstand the elements, including rain, snow, and dust. However, to ensure your antenna performs optimally, keep the top surface and the choke rings of the antenna clean and brush off any ice and snow. A radome is recommended. In addition, ensure the N connector remains clean and dry and replace the dust cap when a cable is not connected.
