Below is a very popular desktop wifi jammer: the 250W High Power Waterproof 300 Meters Signal Jammer with Omni-

directional Antennas. Have you ever considered that when you need a jammer you can find a store that allow you to

choose the jamming frequency bands and then do the frequency bands you have selected for you? This is not a dream

now and just here this 250W High Power Waterproof 300 Meters Signal Jammer with Omni-directional Antennas that you

are viewing here just owns the functions.

This 250W waterproof signal jammer is really powerful and can allow you to choose four or five jamming frequency

bands among the following frequency bands CDMA, GSM, DCS, PCS, 3G, WiFi, GPSL1, 4G LTE, 4G Wimax, and CDMA 450, in

this case people can just tell the four or five jamming frequency bands they want. Thus you can also turn on or

turn off the frequency bands according to the real needs as well without affect the jamming functions of other

frequency bands at the same time for this signal jammer with Omni-directional Antennas.

Thus good cooling fan system and waterproof design has also been used on this 250W waterproof

wifi signal jammer as well so that it can easily work

outside and also and owning the VSWR circuit protection to ensure system will not burn out should there be antenna

short circuiting or disconnection is a merit of this 250W waterproof signal jammer. With such kind of excellent

design, for places such as the meeting rooms, prison, museums, training centers, factories and more this high
