After examining the condition of many of the radars, it was determined that a major effort should be put into repairing the antenna array at Wallops Island. This effort also follows work done by Mike and Ethan along with Rob Pfaff to get the grounds around the antenna arrays cleared out and maintained in late 2016 and 2017. During this trip, Mike and Kevin took stock of what exactly needed to be repaired on the antenna arrays and get some order sheets going. With additional time, the RF performance of the transmitters and antennas would be measured to quantify the amount of repairs needed. Dr. Ethan Miller and Dr. Patrick Dandenault from APL joined us for a day to review the antenna array repair project.

Following the May 2017 trip, the west main reflector array still needed to be rebuilt with a little over half of the wires still needing to be strung up. This trip would also serve as the last tune up of the radar prior to the Great American Solar Eclipse of 2017.

Following the November 2016 trip, the correct size (5/8” rod) of CADweld mold was ordered in order to complete the grounding work that had been long overdue. However, winter cold and wet set in and so the work could not be completed until better temperatures arrived. In the month prior to this trip the internet connection to the site had been out for several days if not weeks at a time going on 3 to 4 weeks. So with these issues, a trip was planned to take care of these issues and make sure the radar was running fairly well (with known issues on the antennas).

Hays, KS sustained a major freezing rain and icing event in mid-January 2017. Following reports from FHSU student intern, Brett Chrisler, of significant damage to the West main antenna array a trip was made by engineer Kevin Sterne to assess the damage at the radar site. As well, this trip would be allow for preparations to be made for a future repair trip.

After many, many years, the grounding work along the antenna poles had not been completed. On each antenna pole, a ground rod had been driven into the ground and a copper busbar had been attached under one of the bolts on the base of the pole. So a trip was made to the site by Kevin Sterne, Shibaji Chakraborty and Muhammad Rafiq to complete the grounding work.
