SESP develops and manufactures the most effective
and reliable radio frequency jammers in the world.
SESP’s very-high-power broadband jammers, the 200S series, provides unparalleled anti-terror security and VIP protection in large sensitive locations, such as government facilities, military installations and embassies. 200S series jammers are also suitable for installation inside military shelters (operating from AC mains power).
Four broadband jammer models in the series provide varying levels of coverage suitable for any fixed-location installation. The most powerful model, the 203S, is capable of completely and simultaneously paralyzing all communication frequencies from 20MHz to 3000MHz, without “gaps,” at 1365 watts of total RF output power. Jamming of each frequency band can be activated or deactivated independently
