Microwave Grounding - 2008

The microwave communication tower, which stands near to the VATT building, was found with a 56 ohm ground impendence that did not meet the Motorola standard of 25 ohms or less. Our investigation showed the cause of this problem to be that the chemical ground was destroyed, exposing the observatory to a lightning risk. An extensive repair plan was implemented by the VATT, and with the help of MGIO and the LBT group, the microwave tower grounding scheme was repaired and improved to 0.5 ohms. This is well within the Motorola standard. The VATT team on this project consisted of Franz, Gray, and Duffek.
