ET108 Cellphone signal isolator is independently developed by us by aiming at covering large open outdoor area as a hi-power mobile communication signal isolating system, which is mainly used in large jail playgrounds, lawns, and special actions against illegal assembly and safety accidents by the internal guard troop of armed police, troops?field manoeuvres and camp and field training, for eliminating hidden safety troubles and adverse factors resulted from using of mobile phone in these areas. Hanllow has successfully and finely developed this hi-tech. product according to the actual domestic situation for mobile communication. It can isolate GSM/CDMA/DCS/PHS/PCS mobile phone signal within a oval range of 80-150m (1000-9000 sqm.) radius, making mobile phones can not be dialed out or receive call or message, while not interfere with the work of other electronic equipment, and the mobile phone can restore to be normal when leaving the isolating range. It adopts double frequency directional antenna used by external base stations, this hi-power unit can be installed in vehicles, convenient to operate and safe to operate. The predecessor of the product is relatively small in power and isolating distance (USP power supply no included), it gains shares in the international market for its small volume and light weight.

Key Features

l          Adopting hi-frequency broadband interference technology, just interferes the down stream, not the base station. The total single unit TX power exceeds 60W, and the top power is 100-120W.

l          Divided into 900Mz/1800Mz double channel output or CDMA/GSM/DCS/PHS four channel output; and the average nominal output power of a double frequency directional antenna is about 30-60W.

l          With high effective power (channel power), big interference radius, effective isolating distance 70-150m, signal field intensity -65～-80dBm.

l          Imported components and the slow activation circuit design can avoid sparkles generated by the mechanical switch, highly integrated and stable in operation.

l          Adopting 20W stand casing. UPS power supply, 24V100AH chargeable battery is selectable.

In the course of normal use, the range of 1.4m front and 0.2m side and back of the antenna should be free of people existing there for long times.
