Joe Palaia Park, formerly known as Deal Test Site, is a local park. Deal Test Site? It’s in a town called Deal, fine, but what were they testing?

Western Electric purchased a farm in 1919. After WWI, AT&T used the site for wireless experiments. In the 1930s, Bell Labs developed microwave radio systems for long distance phone calls (a system which was eventually replaced by fiber optics). And in 1953 the site was leased to the U.S. Army Signal Corps for tracking satellites (including the Russian Sputnik I and Sputnik II).

According to Wikipedia, when AT&T was doing their ship-to-shore wireless testing, they erected five big radio towers, which were used to broadcast speech and music for a range of 1,000 miles. These are a few of those towers.

So basically, these towers are representitive of all the communications testing that was going on here back in the day.
