Antenna beam rotator, yagi pmr446 70cm etc

cults3d

I built a low-cost and easy-to-make antenna rotator for small beams. This was created and used to power a small directional antenna I designed myself. Driven by a simple RC servo, I used a metal gear digital servo LewanSoul LD-3015MG and initially controlled it with a basic servo tester before upgrading to an Arduino for better control and the ability to scan. The rotating shaft is just a length of 8mm diameter aluminium rod pressed into a printed gear and rotates on two 608 skateboard bearings. I then made a magnetic mount to accept the rotator for use with my car on high ground. The legs are 16mm carbon fibre, each foot fitted with two 15-long by 10-diameter neo magnets. This project should be of some use to others; feel free to ask any questions you may have. Bob Here is a video clip of the rotator in action: https://youtu.be/ZqkdOfleg3A
