Doug N1LIs tower has a pair of large single-band Yagis mounted on ring rotators: one at the very top and one about half-way down the tower. You can also check if its locally available. FIGURE 2A. Most of the analog meter scales for the popular Ham-IV and Tailtwister rotators are north-centered with north at the top and south at either end of the scale. In-Tower Wind Load, Incl.
Wear is accelerated by de-energizing the solenoid while the mast is still turning, causing the brake to impact the sides of the indentations. The rotator can handle a bigger wind load when mounted inside a tower section because the tower holds the mast in place straight above the rotator.
This eliminates any sideways load on the rotating assembly relative to the base. Keep in mind that if the distance between the control and drive units exceeds about 150 or 180 feet, you should be using rotator cable thats heavier than 20 AWG.
When the rotator turns, the discs move apart to let the mast turn freely. If you are an international customer and would like to change the currency that prices are displayed in, you can do so here. They are inexpensive and suitable for small Yagis or log-periodics for VHF through microwaves.
Hams cant use as much power as some of the other communication services, so they use antennas to get through by focusing radiated power.
