The heck it is, that Israeli fence is an engineered fence. As to a contractor all we have is his assertion there is no name to check out. It is not a matter of any fence it is the fence he has collected money to build. If he ends up with 4 miles of cattle fence again he is still defrauding the people that gave him money.
Cattle fence, like in Texas, is widely available. Simple barbed wire, and 5 strand wire and fencepost is off the shelf just like Texas.
About 160 feet wide, with overruns a bit over $2 million/kilometer.
