ALMA. Antena Mitsubishi Electric de 7 m
Hello everybody!
Here again. To release my hand in my return to modeling on cardboard, I decided on two models. The first was the Apollo-Soyus project and then what I will present now. I thought it easy, but no. The difficulty was greater than expected. It is the 7-meter Mitsubishi Electric Antenna of the ALMA complex |

ALMA, Antena Mitsubishi Electric de 7 m
ALMA (Atacama Large Millimeter / submillimeter Array) is a giant radio telescope composed of an array of fifty 12-meter antennas, as well as a smaller array known as the Compact Atacama Array (ACA). The latter will have a total of four 12-meter antennas and another twelve with 7-meter discs.
The antenna I built is the latter. Here are a couple of photos of the real antenna: Last edited by ConstOrion; 07-08-2021 at 06:13 PM. |

Before, point out what a big difficulty the manual was: in Japanese. The translators did not help. I started with the main reflector, the sub reflector, and the sunshade.

After searching the net, I found a manual in Spanish of an ALMA antenna model, but the 12-meter one. For some pieces that I have already assembled and the one that comes, it helped me a lot since they are similar in their construction.

We continue with the Yoke and the azimuth bearing housing

From now on, I had to assemble based on ingenuity and look a lot at the photos of the antenna, because the manual in Japanese did not help much.
