BIG-RAK HR
Rotor works with controller Rot1Prog. It it can be used for lightweight construction, 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 long life and durability of the device. Its advantage is the possibility to adjust the worm and worm wheel clamping, 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.

Controllers
| MD-01 | |
|
MD-01 is an electronic driver used for turning rotors. It is a multifunctional device, allowing for various combinations of work setting. The driver may be connected to two single rotors (e.g. two Azimuth rotors) or double (one Azimuth / Elevation rotor). The basic circuit provides operation with direct current motors. |
