Brief:
This antenna is mainly used for time-issue, communication and navigation. Compared with other antenna
in the same frequency, it’s highly effective, broad bandwidth and smooth
impedance curve. Antenna top shapes in square and 8 down-lead wires furled near
the ground and are connected to the transmitter.
As the broadcasting antenna , it has continuously been in use for 30 years,
with highly reliable performances.
