H.F.
LOG PERIODIC ANTENNA
Model
No. H 609
3.5 to 30.0
MHz
The
H.F. Log periodic Antenna, is operative, in the frequency range
3.5 to 30 MHz, with un-usual features including broad band width,
good directivity and uniform performance throughout the specified
bandwidth. Its unique design eliminates the usage of a number of
frequency resonant antennas. The antenna occupies a total area
of 90 Mtrs. X 85 Mtrs, with mast height of 24 meters.
