The Inhibitor TriBand high power unit provides a unique solution for coverage of large areas by using a dual transmitter generating upto 30W of jamming power over the desired cellular frequency bands.

The high power unit incorporates a metal shielded cage comprising two jamming signal generators,each connected into a 15W booster power amplifier,thereby enabling the transmission of up to 15W per frequency band.The cage is attached to a metal heat sink for heat dissipation under continuous operating conditions.

Standard units are housed within a robust Pelican case and powered by mains AC voltage (110/220).
The filtered output signal is fed into directional antennas installed within the Pelican case,opposite the heat sink side.Each unit has VSWR protection that disables
transmission in the event that no antenna is connected to the RF output connector or in the event that antenna transmission is obstructed by a close object.

Optional configuration may include external N-type
RF connectors for the use of external ntenna(s) instead of the unit's internal antennas.

The output signals of different frequency bands may also be combined using a diplexer so as to enable
the use of a single wideband antenna.(eg:900/1800).

Further optional configuration may include DC input operating voltage (12/24V) to allow vehicle operation. Another available option is an internal battery power unit,allowing portable operation of approximately up to 1 hour without any power source at full transmission power.Battery operated units may be recharged by either mains (110/220V)power or DC (12/24V)power, provided that the unit is in recharge mode and not transmitting. An optional trickle/fast charger enable battery recharge,while the unit is operating.

Designed for versatile use,the high power unit may be either deployed as a fixed installation (wall or rack mounted),vehicle mounted (by using vehicle's DC power feed and external magnetic base antenna)or portable use (by using a battery operated unit).

Each unit's jamming signal generators covers a different cellular band
eg: (00/900/1800/1900) and is configured for optimum coverage of the specific sandard(s) available in the respective band (eg:GSM/CDMA/TDMA).

Additional frequency bands and/or cellular standard are available upon request.As third generation cellular technology (G3) is deployed,additional frequency bands will be offered. The jamming signal generators are built using PLL synthesized technology to ensure high accuracy and stability during operation.This ensures that the unit's transmitted jamming signal blocks all cellular signals without interfering with other vital wireless communications.

An optional infra-red remote control enables digital power control of each jamming
signal generator up to the maximum output power,as well as other transmission
parameters such as centre frequency,span & modulation characteristics.In order to
disable the operation of mobile phones,the jamming signal,when recieved at the mobile
phone's antenna,should have sufficient strength in comparison with the radio signals
transmitted by the cellular network's base stations.Since the high power unit's
maximum output power is fixed,the actual jamming range in any given location is a
function of the signal strength of each cellular network as received by mobile phones in
that location.The signal strength is mainly a function of the distance from nearby
cellular base stations.Therefore,in principle,the closer the base station,the lower the
jamming range and vice versa.
