Never heard of the term “fta” before. I assume it’s free to air, but still clueless to the size of reflector #3 requires. One would be better off using the real deal linear actuator on C band, than hacking a cordless drill. While the motors #4 mention are geared down, they are still plenty fast at the point where a hacker can tap the motion.

This to poster#3, Alexander. Neat idea on the drills especially if you need remote with small battery backup..you just gave me an idea for something unrelated.
But, have you ever tried automotive windshield wiper motors or power windows motors … already geared down :) 12volts from somewhere and good to go.

O man that's really nice!
Beautiful bit of work there!

I was never big on hf, but I do have a dipole strung up in my attic for SWL stuff.

The other day, when I was pondering one of the FTA satellite network… I was wondering if making my own movable dish would be as easy as taking some 15 dollar 18v cordless drills from Harbor Freight and gearing them down a whole bunch.
