Anti-jamming radio



SW Radio Africa is still being jammed very effectively. The two designs for anti- jamming antennae in the accompanying Word document are not my own ideas but are taken from webpages that are in the public domain. If you wish to visit the sites concerned, follow the two links pasted here.

As a result of the nature of the jamming transmitters and the way that short-wave frequencies work, (I don't wish to go into a long-winded explanation) if the antennae work at all in this situation, they will work probably most effectively on the frequencies in the 25m waveband that SWRA are currently using, and any higher frequencies. They are cheap and very quick and easy to make.
