See microwave antenna used 63 years ago

I'm sure you have taken note of the circular antenna on telecommunication towers (mast).......ok.....those are microwave antennas used to transport data from point to point. They vary in size depending the traffic to be transported, enough said. Below is a microwave tower 63 years ago. AT&T launched a microwave relay-skyway, a network of 107 microwave towers at an estimated cost of $40m and this towers have been abandoned today with modern day microwave links taking over.
