PKI 4345 is versatile and effective in use. It can be installed using a tripod or with a fixed mast mounting. PKI 4345 blocks the communication link between the drone and the remote control by sending electromagnetic signals, thus interrupting the reception of satellite navigation signals. This forces the drone to return or land immediately. PKI 4345 transmits on the frequencies 800MHz, 900MHz, 1.5GHz, 5.8GHz, covering most of the UAV communication and navigation frequencies. Special frequencies can also be supplied by PKI on request. In conjunction with a pan/tilt head, PKI 4345 can quickly and accurately aim at and control the drone. With a jamming range of 3000m PKI 4345 is one of the strongest of its type, equipped and integrated with the special multi-band antenna, control board and power jamming unit.
