Advantage: Output power total 80w, You can choose high gain 5-7 dbi OMNI or Panel directional antennas, shielding 30-200m,Still depends on the strength signal in given area. Each unit can jam up to 6 frequency bands simultaneously, each frequency band is separate and with adjustable power from max to off (0), LED indicator lights display power supply. 100% safe VSWR over protection (isolator) for each modular. Big aluminum alloy shell and cooling fans, not-stop to work. Selection of antennas to provide more flexibility regarding jamming coverage.
