The Adcock antenna array has been widely used commercially, and implemented in vertical antenna heights ranging from over 130 feet (40 meters) in the LFR network, to as small as 5 inches (13 cm) in tactical direction finding applications (receiving in the UHF band).
•
The LFR remained as the main aerial navigation system in the U.S. and other countries until the 1950s, when it was replaced by VHF-based VOR technology.

The LFR remained as the main aerial navigation technology until it was replaced by the VOR system in the 1950s and 1960s.
The first was the presence of an Adcock antenna, an arrangement of four masts that allowed the signal to be directed through phase differences.
