Advantages: 12 chancel design, 3-10watts each band High output power, Total up to: 90W, jamming up to 80m (Still depends on the strength signal in given area) External high gain 2-3dbi Omni-directional antennas all the TX frequency covered down link only Built-in good cooling system inside 6 fans, Working non-stopped Built-in AC to DC adapter safer using 2-5meters with Infrared Remote Control Turn ON /OFF Power LED pilot light show each band working status . Can adjust power or turn off any single band without influencing the other bands operation Independent module design with frequency source of each channel, easy maintenance (if have any damaged frequency band, replace with new PCB directly, no need for professional equipment such as frequency analyzer)
