Eight-way Portable Signal Jammer/Cooling System Well Hand-held Cell Phone Signal Blocker




This hand-held signal blocker is one of the most sold products in our handheld models, because this model includes almost all common mobile phone frequency segments, the GPS frequency band Lojack, etc. It is a very good price/performance ratio. The price is relatively economical and can also meet the general signal shielding requirements. The shielding distance is 20M. The distance of this shielding should be determined according to the signal strength of the environment. It may be shielded to 30-50M when you drive outdoors, and the signal environment is relatively clean. You may also be on the mobile phone. The operation of the base station can only reach a few meters. This situation is normal, so please confirm with your customer service and confirm your needs before placing your order.
