Everything about The Ebright Azimuth totally explained
The
Ebright Azimuth is the point with the highest benchmark monument elevation in
Delaware. It is marked with a
geodetic benchmark monument and has an elevation of 447.85 feet (136.50 m) above
sea level. The only state high-point with a lower elevation is
Britton Hill in the state of
Florida at 345 feet (105 m) above sea level.
The Ebright Azimuth is located about 6.5 miles (10.4 km) north of downtown
Wilmington,
Delaware, in far northern
New Castle County, within a few feet of the
Pennsylvania state line. It is near Concord High School, to the north of
Naamans Road, at the middle of the intersection of Ebright Road and Ramblewood Drive. This is an entrance to the Dartmouth Woods development.
Surveying by NGS and DGS personnel indicates that the mobile home park just west of Ebright Road is at least two feet (60 cm) higher than the benchmark.

) The land under the mobile home park isn't "natural elevation" since it's a man-made plateau that was constructed to prevent flooding in the area. Man-made elevations don't change a state's "high point" location.
Contrary to what many people believe upon first impression, "Ebright Azimuth" isn't a person's first and last name. Ebright is the name of the road where the monument is located and also the last name of a local family. However, the term
Azimuth refers to the horizontal component of a direction.

Radio Tower History
The self-supporting
radio tower just south of the benchmark was constructed in
1947 by
Western Union as part of an historic
C-band microwave radio relay system that linked
New York City and
Washington, D.C. This site was assigned the name "Brandywine" in recognition of
Brandywine Creek located several kilometers to the west and was licensed with the callsign KGB29.
(External Link) Western Union's engineers specified a heavy-duty prefabricated
fire tower structure, which allowed the microwave transmitters and receivers to be installed inside the cab.
"Dish" antennas, mounted behind the window openings, were aimed towards the adjacent relay stations at
Mt. Laurel, 54.4 km (33.8 mi) to the northeast, and Elk Neck near
Elkton, Maryland, 49.1 km (30.5 mi) to the southwest.

Like most of their early microwave relay sites, Western Union
decommissioned the Brandywine installation at Ebright Azimuth as more-reliable broadband
fiber systems were developed. The structure now supports several
VHF and
UHF land mobile radio antennas.
