Yaesu G-800DXA Medium Heavy-Duty Rotator Systems
Yaesu G-800DXA Medium Heavy-Duty Rotator Systems are azimuth positioners designed to rotate large tower-mounted amateur and professional antenna arrays under remote control from the station's operating position. These systems feature attractive compass-dial position indication controllers, with a connector port for optional computer interface for automated directional antenna positioning control. Yaesu's G-800DXA rotator design utilizes 98 heavy 3/8 in. dual-stacked circumferential ball bearings to distribute load over the full diameter of the housing. This design minimizes stress and wear and practically eliminates the possibility of destructive water entry: There is no shaft hole in the top of the housing. Instead of the usual AC motor drive used in older rotator designs, the G-800DXA use a variable-voltage DC motor, removing the need for a large starting capacitor with its potential for failure exposed to outside temperature variations. The factory-lubricated rotator unit is housed in melamine resin-coated die-cast aluminum, intended to provide maintenance-free operation under all climatic conditions. A mast alignment gauge on the rotator housing simplifies accurate mechanical alignment during installation. Tower mounted, this model handles over 20 sq. ft. of antenna wind load and over 400 lbs. of vertical mast load. Installation is required for included plug connectors on to the installer supplied 6-conductor control cable; 20 AWG for lengths less than 125 ft. and 18 AWG over 125 ft. Console power is 117 volts AC for units sold in the USA. The handsome desktop controller provides 360 degrees radial indication of actual antenna azimuth bearing. You can select rotation time over 360 degrees from 40 to 100 seconds on the G-800DXA, and preset a desired heading for the rotator, to which it then turns automatically. The operator may select the stop heading, the compass bearing through which the rotator cannot be turned, which is most convenient for their station location and operation, allowing full rotation through north, south or both, if desired. In any case, 90 degrees overlapping rotation allows rotation through the selected stop heading for 450 degrees of total rotation. These rotators are intended for mounting to an accessory shelf inside a support tower (not supplied), at least 1-meter (40 in.) below the top of the tower. Yaesu rotators have a fine reputation within the Amateur Radio community. When installing a new tower, or replacing an old rotator, consider purchasing a Yaesu G-800DXA Medium Heavy-Duty Rotator System from DX Engineering.

Antennas-Amplifiers HF 2500W High Pass Filters
Antennas-Amplifiers HF 2500W High Pass Filters are passive RF devices designed to pass signals above a defined cutoff frequency while rejecting unwanted lower-frequency signals. It is intended for use in environments where suppression of low-frequency interference is required, such as from low frequency (LF) transmitters (30–300 kHz) or medium wave AM broadcast stations (526.5–1450 kHz). These filters are particularly effective in mitigating interference from these sources. An optional notch filter can be implemented to target and further suppress specific AM broadcast frequencies. Measured data for these 5720 High Pass Filters was obtained using a fully calibrated HP8753ES 2-port network analyzer. These excellent results were achieved by careful selection of components and design.
