This
antenna is designed by Defence Electronic Research Labs, Hyderabad,
for receiving operation from 1.6 to 30Mhz. The Antenna adjusts
its effective length for any frequency within the specified frequency
range and provides omni directional pattern. It is provided with
two specially designed frequency, sensitive networks which will
tune only to the desired electrical length of the antenna to resonate
at the desired frequency and thus the variation of input impedance
and existence of nulls are avoided. The antenna provides uniform
performance throughout the band.
The
antenna is divided in to three elements and the two electrical networks
using lumped constants internally gets connected depending on the
frequency of operation. The electrical networks, make the desired
length of the antenna effective, disconnecting the undesired length.
The antenna is provided with an impedance matching transformer and
a lightning arrestor.

The
antenna height is approximately 9 meters and it requires around
38 sq. meters area for installation. The antenna provides almost
cosine vertical radiation pattern and a circular horizontal pattern.
It is portable lightweight and quick to install.
Application: This antenna is very suitable as
a receiving antenna for receiving centers of Broadcasting organizations,
and for any other communication system requiring an all round coverage.
