Most of the propagation enhancement that we may mistake for antipodal focusing is actually via the E Valley/F Layer ducting mechanism. 73 & GUD DX, Thomas F. Giella, KN4LF Retired Space & Atmospheric
Of course there is no contribution from the daylight side - that goes without saying. However, I would say 100% of topbanders would call their other-side-of-the-world receptions "antipodal" and 100%
from I mentioned a few days ago that VK6 is nearly (but not exactly) antipodal to my QTH. Most of the time there is definite directionality to the signals, but it is unpredictable. On short path, it
This may appear obvious but is this ducting the mechanism behind "spotlight" propagation? _______________________________________________ Topband mailing list Topband@contesting.com http://lists.cont
VK3ZL, no where near the GA antipode, skews from SW to NW. Signals from any larger distance, even Europe, skew at large angles at times. The longer the distance and tougher the path, the more likely
Interestingly, the only time I was ever told by stateside stations that my 20 meter signals were equally strong on all azimuths was in late April or early May,1968. My ship was just offshore of 3B9.
