144 Mhz elevation system
In order to void any torsion on the Yaesu G-550 zenital rotor I used a 48 mm diameter "U" pipe made by steel and I locked it to the mast by a clamp. I took that idea from Marco IZ5EME who is using this system since very long time on his 432 Mhz EME array.
I can elevate the array up to 180°, and this is very useful for the upper antennas maintenance.
The azimuthal rotor is the Yaesu G-450.
