Installation of the interferometer ground coax cables went quickly and easily with 4 people at the site. These cables were then measured and trimmed to within a couple of inches of each other for electrical length. The cables were then buried in places to protect the cables and keep the site tidy.

Once the coax cables were installed, the interferometer array antennas were checked and all of them serviced. The general servicing required cleaning contacts to make sure all the radiating elements were making good electrical connections. However, this may need a better modification in the future to prevent repeated need of this maintenance. In addition to this servicing, the feeder coax cables from the base of the tower up to the balun were replaced with new 600 series low loss coax cable. This replacement needs to be performed along the main array, but time would not have allowed the completion of this task.

With the interferometer antennas and ground cables installed, the electronics inside the building were checked to see how well the receiver front end (RXFE) for the interferometer was working. Here the electronics checked out well and some notes were taken on documenting the status of the RXFE. With the electronics running well, the radar began collecting elevation angle data in the later part of Aug. 16, 2018. Measurements taken during this trip along with data analysis will help determine an appropriate tdiff value.

Otherwise, the RF safety signs were installed around the site in order to warn local people about the electromagnetic radiation being transmitted from antennas. A small number of other checks were taken before time at the site ran out. One of the more notable checks was replacing an antenna feeder cable on the main array with one of the old ones from the interferometer array.
