Comparing tropo fade rates of closely-clustered Green Bay TV stations

A comparison of Green Bay TV stations over ~180 mi. tropo to explore whether their fades are in sync or if fades are frequency dependent. These stations were chosen because of their similar power levels, heights, and tight grouping which make them within 5 degrees of each other in relation to the antenna beam. Taken between 1am and 2:30am EST.

Antenna used was UHF Parabolic Antenna w/ 20-22dB reflector.
