DX Engineering Rotator Top HD Mast Clamps significantly improve the connection between the rotator and the mast. The mast gripping pressure of these clamps is completely adjustable, by limiting the torque applied to the included clamping fasteners.

Available in two sizes, for 2 inch OD and 3 inch OD masts, based on the K7NV design, these are the heavy-duty original equipment mast clamps for the DX Engineering RT4500HD Rotator.

The 2 inch OD HD Mast Clamp is also a heavy-duty replacement for M2 Antennas OR2800 Positioners and Yaesu G2800-DXA, G1000-DXA, and G800-DXA Rotators.

Available in two sizes, for 2 inch OD and 3 inch OD masts, based on the K7NV design, these are the heavy-duty original equipment mast clamps for the DX Engineering RT4500HD Rotator.

The 2 inch OD HD Mast Clamp is also a heavy-duty replacement for M2 Antennas OR2800 Positioners and Yaesu G2800-DXA, G1000-DXA, and G800-DXA Rotators.

The 3 inch OD HD Mast Clamp version fits only the DXE-RT4500HD and M2 OR2800.

NOTE: When the mast mounted rotatable antenna(s) installed have a wind load or wind exposure rating of a total of 18 square feet or more, the use of a 3 inch OD mast and mast clamp are highly recommended.

Each clamp plate has holes drilled for the applicable rotators. Clamping bolts are included with each. Also, rotator clamp mounting bolts are included for DXE, M2 and Yaesu (2in. clamps only). Replacements are sold separately... see "Replacement Parts" on each mast clamp detail page.
