144 MHz EME antennas

Autumn is here, and the weather has become rainy. It is frequently blowing and occasionally we have storms. Antenna work is difficult now, especially when you only have weekends for this kind of job. I have decided to mount 2 x 8 element yagis for 144 MHz as my first EME antenna array. The yagis will be vertical polarized, and two rotators will turn the array.

Two 8-element yagis on the ground.
I have replaced the standard 200 W balun on both antennas with high-power baluns from Wimo. I intend to use 1 kW output for EME, and each antenna will be fed with 500 W RF.
