DX Engineering RT4500HD Heavy-Duty Rotators
DX Engineering RT4500HD Heavy-Duty Rotator – The ultimate azimuth positioning rotator, purpose-built to work flawlessly for many years in a majority of tower mounted directional antenna systems. Every aspect of this rotator was designed for high-strength, ease of installation, serviceability and longevity. This rotator is extremely capable and worry-free for tower mast mounted directional antennas. The RT4500HD Heavy-Duty Rotator has capabilities that rival most rotators available on the Amateur Radio market. With an impressive list of features and benefits, it is noteworthy that this rotator does not have mechanical limit switches. Soft rotation limits are set in the optional controller to match the limits of the installed antenna cables. If the antenna or the mast ever slips, simply reset the controller to the new center of rotation and recalibrate the rotational range. Climbing or antenna mast repositioning is not immediately required. The part number DXE-RT4500HD is the stand-alone rotator unit only, which does not include a Top Mast Clamp. This allows for the selection of one of two different size Rotator Top HD Mast Clamps available, both also sold separately, that matches popular mast outside diameters (OD); DXE-RTMC-2 for 2-inch OD mast and DXE-RTMC-3 for 3-inch OD mast. Similar part numbers with added suffixes represent combinations that include the DX Engineering RT4500HD Heavy-Duty Rotator with either the 2-inch or the 3-inch Rotator Top HD Mast Clamp. Other part numbers include either the DXE-RT-21DXE Digital Rotator Controller or the microHAM ARCO Advanced Rotator Controller. Rotator control cables and cable assemblies are sold separately. Features and benefits of the extremely durable RT4500HD Heavy-Duty Rotator: • Superior Rotational Torque > 4,400 in. lbs. with high ratio worm gear drive powered by an extra heavy-duty 24VDC motor • Exceptional Braking Torque >18,500 in. lbs. by high ratio gear reduction that prevents rotation of the mast mounted antenna system due to wind • Very high Vertical Load Capacity — internal needle thrust bearing handles up to 2,000 lbs. • High-compression Heavy-Duty Top Mount Mast Clamps are available for 2-inch OD or 3-inch OD masts • Precision Movement — accuracy within +/-0.1 degrees with high resolution pulse counter • Easy Maintenance — access panel allows service of pulse counter switch without removing the rotator from the tower • Built for Longer Life — hardened steel gears welded onto shafts prevent slippage and shearing of key pins; larger main gear provides increased strength • Weather-Protected — sloped body sheds water; seals at the output shaft, the intermediate plate and the access panel keep moisture out; weep holes make sure it stays dry • Worry-Free Installation — standard four-bolt mount (same as Hy-Gain T2X/HAM); this triangular-shaped rotator fits inside ROHN 25G and Amerite 25 towers and on Accessory Shelves (rotor plates), including the DXE-AS25G and DXE-AS-455G. However, the RT4500HD easily handles antenna systems larger than the 25G will safely handle. Rohn 45G, 55G and up, Amerite 45 and 55, and many other high strength towers are recommended • Works with High-Quality Accessories — Optional DX Engineering DXE-RT-21DXE Digital Rotator Controller, or the microHAM ARCO Advanced Rotator Controller or other 24VDC Pulse Counting Programmable Controller. Install the rotator that provides the most accurate and dependable operations – the DX Engineering RT4500HD Heavy-Duty Rotator.
