Weather, Antennas
Cold front blew through this morning while topoing fill. Strong cold wind swept over the project so much that while trying to hold the rod upright also had to keep one hand on my cap to keep it from blowing away. When I got situated I looked down at the tsc3 screen to see that my error estimates had changed from a 0.03′-0.04’H & 0.06′-0.07’V had changed to a 0.20’H & 0.30’V. Wide open area and horizon at the site. It corrected itself within about ten minutes, but I had never seen this before and wondered if there was an explanation for this.
I could guess that either; I had two separate atmospheres at the time – sort of like a thermocline – or, the antenna hardware took a minute to adjust to the temperature change. No clue here
