PHDI-1890 – IED Jammer

PHDI-1890 – IED Jammer


In order to counter the threat of IED’s, Phantom Technologies has developed and manufactured the IED (Improvised Explosive Device) jammer PHDI-1890 which was designed for Initiating DTMF RCIED’s via V/UHF networks. The PHDI-1890 uses state-of-the art technology for maximum performance.

The IED jammer PHDI-1890 transmits a DTMF signal, which sweeps 125 Channels with a 12.5 KHz hops simultaneously, on all V/UHF communication. The Initiating radius is 250 meters from target (depends on environmental conditions). All two digit DTMF V/UHF will be initiated BY the PHDI-1890.

The Method of operations requires the operator to place the DTMF transmitter at the area/point where there are suspected IED’s and then, start to transmit. Due to receiver limitations, the sweep of all VHF/UHF channels may take some time so that the transmitter will complete the scan of the entire spectrum.
