ku band motors?

Is a ku band motor consider a linear actuator?

No. https://www.google.com/search?q=ku+...ZDjsAScqoGoAQ&ved=0CAkQ_AUoAQ&biw=936&bih=482 vs: https://www.google.com/search?q=lin...pXJsQSPkIHYDw&ved=0CAkQ_AUoAQ&biw=936&bih=482

A linear actuator extends and retracts while a Ku dish (USALS)motor rotates.
Linear actuators require an external 'driver' that accepts diseqc commands and outputs high, 24 to 36 vdc at ~3 amps max, to it's motor. The 'driver' stops when a pulse count sent back to the driver while moving = whats stored in the driver and 'asked for' by the recievers diseqc command. Manual position programming required. The pulse counting occurs in the 'driver', and not the actuator, which only produces them

A Ku dishes USALS motor is automatic in locating satellites after it's aligned to one satellite.
The motor is sent commands (via USALS) to rotate so many pulses, East or West, which are calculated by the USALS computational routine in the receiver. Requires to know where on earth it's located and the orbital position of the satellite desired. The power required, typically being much less, is normally supplied by the receiver(LNB voltage) Ku motors current draw is under 1/2 amp. All the electronics, pulse counting, is within the motor housing.

Linear actuators can move dishes up to many meters in diameter. A Ku dish motor is typically able to move a dish up to 1 or 1.2 meters. (In hobbyist 'form')
Hope that 'worked'.

just wondering. thank you fat air.
