EME Station 2.0 Part 10 – Antennas On The Tower

After a year’s worth of planning and 10 months of construction, we have our new 2m EME Antenna System installed on our EME Tower and working! This stage of our project took about a week…

We’re making good progress on a new 2m EME Antenna System here at AB1OC-AB1QB. Our Antenanns system is up on our EME Tower and we are working through the setup and integration of the equipment and software for our EME Station.

We rented a boom lift and worked with Matt and Andrew from XX Towers to get our Antenna System up. Our antenna installation took a week to complete and it turned out quite well.

You can read all about this step in our project via the link above. We should have the work needed to bring the rest of our EME Station together sometime during the next few weeks. We can already receive signals that other Hams are reflecting off the moon!

EME Station 2.0 Part 9 – H-Frame Assembly

The final major component in our 2m EME Station Upgrade to be assembled is the 2MXP28-32-2X2-3K H-Frame which will support our four 2MXP28 Antennas. The H-Frame is one of the most mechanically complex components in our EME antenna system…

We are almost ready to put our new 2m EME Antenna System. We’ve been working to pre-assemble and test all of the components in the new Antenna Array. The last major component to be prepared in the H-Frame assembly which is used to mount our four new antennas on our Tower. The H-frame component is one of the most mechanically complex parts of our Antenna System. The link above shares all the details of this part of our project.

We are continuing to make progress on our 2m EME Station build. The latest step in the project was to assemble and test the Elevation Rotator and the MAP65 Preamp System. The article at the link above explains what we did to complete this step in our project and to test what is a major sub-system in our 2m EME Station.

EME Elevation Rotator
MAP65 Preamp Housing

This part of the project includes installation and testing of the MAP65 EME Preamp Housing on the rotator assembly. This unit and the rotator are tested along with a Green Heron Engineering RT-21 Rotator Controller and a MAP65 EME Sequencer.

We are getting close to installing our new 2m EME Array on the tower. The final preparation step in our project will be the final assembly and preparation of a large H-frame that will mount the four antennas in our EME Antenna Array.
