Andress Technologies K7NV Mast Clamps for Rotators Now Available at DX Engineering

Some of the best answers to Amateur Radio problems come from operators who have devoted themselves to solving highly specialized equipment issues for their fellow Hams. Such is the case with Kurt Andress, K7NV, a longtime enthusiast with decades of experience converting propeller pitch power units into high-quality antenna rotators, as well as producing other innovations.

DX Engineering is pleased to announce that it is now a reseller of one of K7NV’s signature upgrades: Mast Clamps for rotators. The heavy-duty clamps replace stock units installed on the top of M2 Antennas OR-2800 Positioners and Yaesu G2800-DXA, G1000-DXA and G800-DXA Rotators.

These are direct bolt-on replacements for the stock M2 OR-2800 or Yaesu DXA series rotator mast clamps, significantly improving the mast connection to the rotator and preventing mast slippage that can result with larger array setups. The mast-gripping pressure of these clamps can be adjusted by applying more torque to the included fasteners.

Clamp assemblies have a clearance hole in the center to fit over the bolt and bushing that holds the rotator output shaft up to the base plate of the OR-2800. The mast clamp plate has separate holes drilled for M2 or Yaesu rotators. The clamps accommodate 2 inch diameter masts. They are compatible with either 6 inch round or 6 inch x 8 inch oval OR-2800 base plates, as well as the heavy-duty Yaesu DXA series.

Bolt kits for mounting K7NV Mast Clamps to either M2 OR-2800 or Yaesu DXA rotators are available separately from DX Engineering.
