EME Antenna Failure

DK7ZB YAGI destroyed by snow storm (winter 2013)

After 4 years of use without any problems, my antennas died from extremely strong wind.
It's time for an upgrade:

- better H frame.
- new rotor with braking mechanism, AC motor.
- better coaxial relay DIN 7/16 connectors.
- improved coaxial cable: 7/8" TX, 1/2" RX .
- precise inclination sensor ADXL345.
- Arduino Rotor Controller - internal Moon/Sun Tracking (GPS Syncronization).
