Description
The BIG-Rak rotator works with controller Rot1Prog. It can be used for rotating antennas, such as Yagi and heavy shortwave antennas. It is based on the worm gear, worm, and worm wheel made of steel (as pictured). These features ensure the long life and durability of the device. Its advantage is the possibility to adjust the worm and worm wheel meshing, clearing backlash in the drive mechanism, which may be necessary in the case of wear and tear after long-term use. The device surface is covered with powder coating, effectively protecting against corrosion. Range trading is protected by limit switches. Spares are readily available from stock.
