In occupied Europe the Nazis attempted to jam broadcasts into the continent within the BBC together with other allied stations. As well as increasing transmitter electricity and adding more frequencies, attempts were being manufactured to counteract the jamming by dropping leaflets in excess of metropolitan areas instructing listeners to build a directional loop aerial that will help them to hear the stations throughout the jamming. Within the Netherlands such aerials have been nicknamed "moffenzeef" (English: "kraut sieve").[9]
In terms of shielding assortment, tiny energy signal jammers are commonly Employed in evaluation halls, with one system installed per classroom, masking a place of around 200 sq. meters. On the flip side, substantial electricity total band signal jammers can attain a shielding distance of 300-four hundred meters, with regards to the regional signal power.
