OK maybe it won't take that long I received a response to the question I asked, "is the terminator just panels bought from China manufacture together with a bracket and sold as a Horizon antenna"?
Well I won't give a direct quote because it was a private email but here is what was stated.
"The terminator is much more than that the terminator is built and derived up to Wi-Fi panels that are reconstructed internally and fine-tuned to produce the signal strength that is achieved and put into a nice easy to use package. Although the price of this is more expensive than buying two cheap panels, as demand in sales for the terminator go up the price will come down. If you were to buy the cheap panels you would not be able to reproduce even close to the distance that the terminator will produce. And regarding the holes in the bottom of the panel both will not be in future models those will only be noticed in early Prototypes."
So I take from that, that the terminator is more than just cheap Chinese panels it's actually had to be rebuilt and fine-tuned
