Tropospheric Ducting

[HDTV Forum]

Over the past few weeks I've experienced intersting reception issue since I re created my antenna set-up outside as opposed to in the attic.

Specifically, here in Tampa/St. Pete, I've received DT stations from Ft. Myers (100 miles) and Orlando/Clermont (over 110 miles in one case). Being curious, I searched the internet and found this web site

which actually seeks to predict the phenomenon. Basically, weather conditions can beat the "curvature of the earth" problem in receiving distant stations. since my antennas (two on a combiner) are only 20 ft off the ground and NOT long range type antennas, I was curious if anyone else had experienced this. the stations scan in for about 30 minutes to an hour and a half and then are gone. I've gotten signal strength readings of as high as 77% from Ft. Myers.

Anybody else seen this sort of thing?

I am in central Illinois and during the warmer months the Tropo can be quite strong, I have received stations from Detroit, Minneapolis and very frequently Chicago and St.Louis, with a rotor and good Tropo you never know how many stations you can get.
