This article says SHF freqs cannot 'skip' but this article from pop science counters that... http://books.google.com/books?id=Bd0DAAAAMBAJ&pg=PA84&lpg=PA84&dq=Over+The+Horizon+Microwave+Relay+telephone+system&source=bl&ots=Sj007xmk74&sig=v9oc5yX1udzefmS6SnwwzuEVmjc&hl=en&sa=X&ei=TZN0UdeIA4bJ0QGA-oCoDA&ved=0CGEQ6AEwBg#v=onepage&q=Over%20The%20Horizon%20Microwave%20Relay%20telephone%20system&f=false — Preceding unsigned comment added by 220.127.116.11 (talk) 19:40, 27 May 2013 (UTC)
- First of all, whatever the effect they are getting there, it is not skywave skipping. They are using some huge transmitter powers for tiny received signals. It sounds more like tropospheric scatter to me although the engineers involved don't seem to know exactly what it is. Secondly, most of the frequencies cited are not in the SHF band, the are in the UHF band. The highest frequency cited is 3700 MHz, which is only just inside the SHF range.

UHF or SHF?
This article claims that "This frequency range is used for most radar transmitters, microwave ovens, wireless LANs, ", the frequency range being 3GHz to 30GHz. However, microwave ovens and most wireless LANs operate at around 2.4GHz in the UHF range, as stated here:
