This set of rings are used in installations where the ground may have shifted or other condition may have caused the levelness of the mounting platform to be imperfect.
The set of counter milled rings with 32 holes allows for incremental adjustments to the levelness of the mounting platform for the TACAN antenna. With 16 positions between the maximum and minimum positions, the 1.5° of total levelness range can be adjusted in 3/32” increments.
Size and Weight: 41.50” OD x 36.00” ID x 1.00”, ~25 lbs. (each ring)
