I'm running that RCJ40-D for almost a month and I can say that it does its work great! It was bought for the only one purpose - to jam Wi-Fi connections of the executives at my office, because I care about network's security. I've tried to prohibit Wi-Fi but some people still have forgotten to turn off the Wi-Fi module. Now I turn it off myself. I just turn all the antennas except Wi-Fi off and everything works great except Wi-Fi. Thanks!
