The antenna is located at the FAA's Leesburg en route control center
(ARTCC). Each of the 24 centers has one almost identical to it. FAA
uses HF as a back up link between centers, The LPDA is 3-30 Mhz. The
Leesburg antenna is usually pointed at the New York ARTCC. All are
rotatable. If I remember correctly they run up to 5 kw transmitters.
It can also be used to contact off shore aircraft on hf, although that
is a secondary purpose. They use other antenna fields for primary hf
air to ground. Domestic air to ground is all vhf. Each ARTCC has many
remote vhf transmitter/receiver sites for air to ground, linked back to
the ARTCC by wire or microwave.
