[QUOTE="Terryl, post: 984752, member: 369937"] Well you can go real cheap (under $100 US) or go real expensive (over $1000 US) depending on what your trying to rotate. The cheap ones can hold up a large deep fringe TV antenna, the big expensive ones Hams use can hold several hundred pounds (in a tower using thrust bearings) one of mine is about $450 US, it holds two beam antennas, one for 6 meters and one for 2 meters/ 440 MHz (combo beam) on a tower. The other is from Hi-Gain and is around $150 US, it holds the stacked array of TV antennas. The one for the ham antennas can rotate 450 degrees either direction from due North. (you have to swing it back to North before going around the other way) The TV rotor can rotate 355 degrees from were ever you set it to as a starting point. All are based on the total wind load of the antenna structure and amount of torque your going to put on it.(Torque is how much the rotor can stop) some of the bigger Ham rotors can hold up to 650 pounds with a total wind load of 32 square feet. If your array weighs 50 pounds with a total wind load of 10 square feet or more then you need the bigger rotor, if just a standard deep fringe TV antenna on a short 1 foot standoff mast then you can use a cheap one. The cheap ones can use a mast of about 1-1/2 inches, the larger Ham rotors can use up to 3 inches or more. The ChannelMaster CM-9521a is about $93 US at Walmart it can hold about any TV antenna made.
