SPID RAU NEW GENERATION Antenna rotor

SPID antenna rotors

The SPID rotors are medium heavy duty in the same class as those of the HyGain type TailTwister or the Yaesu type G-1000/2800DXC me with advanced digital features. Mechanical complexity is reduced to a minimum by using a double bearing system. The position reading is acquired by a solid magnetic reed switch, with a resolution of 1 degree.

The controller is complemented by several features, including digital readout, software control and an integrated PC interface (USB). It is capable of emulating Hy-Gain, Yaesu and Orion rotors, and is compatible with almost all software. The features of the Controller make it easily upgradable with a PROM plug-in.

The Rotors require an external power supply of 12... 24V DC, it is also possible to power it at 12V for any portable uses with reduced torque and a greater rotation period.

The torsional force is approximately 350Nm (3,200 lb-inch), with power at 24. It is significantly greater than any other rotor of the same class and in the same price range

The BIG-RAK and BIG-RAS rotors are characterized by having a very high rotation and braking torque and are designed for use with large antenna systems.

Thanks to the double worm screw and the same magnetic sensor as the RAK/RAS models, the BIG version has the same 1° resolution.

The new RAU compact rotor is designed for smaller antenna systems for VHF and microwave.

• Optional mouse control with 6 user programmable presets

Applicable for simple installations such as yagis or other heavy shortwave antennas. The mechanical parts are toothed mechanisms made of steel (as shown in the figure), which guarantee long and continuous work and high reliability. The advantage is that they can be aligned eliminating slippage that can appear after a long period of use. The surfaces are treated with anti-corrosion paints.
