- There is no reason but stupidity and cost as to why more jammers are not deployed. The Israelis have used them for over ten years to successfully limit their vulnerability to IEDs.
jammer
noun; clipping
A jamming device used to block radio frequencies and other electromagnetic energy. This word is a shortening of the phrase radar jammer. The word jammer is a neologism formed by making jam, a verb meaning to cause or make a working device nonfunctional, to lock, into a noun. This is done by adding –er, meaning one that performs an action, to the end of the word. With the –er ending an m is inserted.
Etymology : jammer. Clipping of 'radar jammer'
