Wind Turbines are a threat to Homeland Defense. They can produce large Blind Spots on Radars - above, infront and behind them - so yes they can cause problems to RF signals.

Trevor,
That is some pretty good stuff for higher powered xmitters...But I doubt there is any instrument sensitive enuff to measure the reflection potential from any satellite we will ever launch, and the "shadow" that it would cause on a LEO is in less than a second...HEO's may take a little longer....
This is conjecture based on my HS physics...I would appreciate comments from any of the many engineering experts we have on here...

?????????????????????????????????????????????? WB6LLO,
1. I have to admit I do not understand your term "reflection potential from any satellite". I would greatly appreciate an explanation of this effect and how to calculate its magnitude on a received satellite signal.
2. How do you calculate the "shadow time" (of this QRM?) to be less than a second?

PS: Checking your QRZ entry and your bio reminds me that I learnt to fly "Stringbags" in WW2. But the war ended before we were deployed to a carrier. I should have been older or declared a false age to join.
