75 Rotator Replacement Potentiometer If you’re using a model 1022 or 1032 TIC Ringrotor, then Mother Nature probably makes you replace your position potentiometer a lot. Make fewer trips up the tower with this fully weather-sealed replacement pot from DX Engineering. DXE-TICGEN-POT Rotator Replacement Potentiometer ...............................$26.99 Heavy-Duty Mast Clamps for Rotators DX Engineering Heavy-Duty Mast Clamps for rotators provide a major performance upgrade over factory clamps. These direct bolt-on plated steel clamps for 2" and 3" diameter masts replace stock units installed on top of M2 Antennas OR-2800 Positioner Rotators and Yaesu G2800-DXA, G1000-DXA and G800-DXA rotators. They also work with DX Engineering's RT4500HD Heavy-Duty Rotator. The clamps improve the mast connection to the rotator and prevent mast slippage that can result with larger array setups. Pressure adjustments can be made by applying more torque to the included steel fasteners. Brand-specific bolt kits for mounting the clamps are sold separately.

One RT4500HD purchaser summed up the rotator this way: “Best rotator on the market! This rotator delivers in every category that is important to someone looking for a well-engineered, permanent, and worry-free solution to rotating a large array.” You, too, can enjoy these class-leading features: • More than 35 square foot wind load rating (inside tower) • Needle thrust bearings handle up to 2,000 lbs. of vertical load • High ratio worm gear drive powered by a heavy-duty 24 VDC motor provides superior rotational torque (> 4,400 in. lbs.) and braking torque (>18,500 in. lbs.) • Accurate within +/-0.1 degrees with high-resolution pulse counter controller • Unique removable panel allows access to pulse counter switch without removing rotator • Ability to set sof limits—If the antenna or mast ever slips, just reset the controller to the center of rotation and recalibrate the rotational range • Hardened steel gears welded onto hardened steel shaf s prevent slippage and shearing of key pins • Sloped body sheds water; seals at the output shaf , intermediate plate and access panel keep moisture out; and weep holes make sure it stays dry • Ideally sized to fit inside ROHN 25G but easily handles larger antenna systems For complete details, enter “RT4500HD” at DXEngineering.com.

These solidly built options significantly improve the connection between the rotator and the directional antenna rotating mast. The clamps mate with the DX Engineering DXE-RT4500HD Heavy-Duty Rotator and replace the clamp on the M2 OR2800 Rotator. DX Engineering highly recommends installing a 2.5" or 3" O.D. mast with its Rotator Super Mast Clamps whenever the installation of mast-mounted rotatable antennas will have a total wind load or wind exposure rating of 18 square feet or more. Kits come with two rugged aluminum clamps for the standard version and three for the heavy-duty model, stainless steel backing plates, stainless steel bolt sets, and fasteners. The clamps' special surface texture provides a secure fit that resists torque, wind, and weather. All models can be used on Rohn 45 and larger towers. Only 2" versions fit Rohn 25G towers.
