No. H 207
Cat
No: AERIAL OUT FIT AEV ( 1 ) (3 to 30 MHZ.)
AIR
FORCE: 310 B/5985-000323 (3 to 30 MHz.)
Cat No: AERIAL OUT FIT AEW ( 1 ) (10 to 28 MHz.)
(Defence Approved)
The
Monocone Antenna is unique in design and construction provides unusual
broad band width and uniform electrical characteristic throughout
the frequency band without requiring any adjustments. Two structures
are designed, one covering the frequency range 10 to 28 MHz, with
a height of 8.25 meters and the other covering the frequency range
3 to 30Mhz, with a height of 21 meters.
The
antenna, Monocone, is omni directional in propagation and is designed
with a feed point impedance of 50 Ohms. The Antenna is designed
and useful for transreceiving in defence and civilian organization
to whom broad band width in the H.F. range is required.
N.B:
This is a Defence Design of DLRL. The antenna is made according
to DEF/ MIL/ JS specification.
