If I could give a 0 rating I would. The light blinks green constantly meaning there is signal "oscillation" according to the guide and online instructions. I've seperated the antennas as far away as 70 feet horizontal combined with another 25 feet vertically. Even without the indoor antenna plugged in it blinks. I've tried a different outdoor yagi antenna and a different indoor antenna. As soon as you plug the outdoor antenna in it starts blinking green. ZERO SIGNAL IMPROVEMENT. In fact, if I hook it up to the router (as shown in the installation guide) the signal drops to zero and data goes away all together. Sending back and getting refund.
