LOG PERIODIC DIPOLE ANTENNAS
FROM 30 MHz
TO 18 GHz
Antenna design and Manufacturing
Corporation’s BROADBAND LOG-PERIODIC DIPOLE ANTENNAS
are designed for RFI/EMI Testing per MIL-STD- 461/462,
Tempest Testing, Surveillance, frequency Management and
Electronic warfare applications in the frequency range
from 30 MHz to 18 GHz.
Antennas above 100 MHz are of variable slant,
linearly polarized and produces fully developed
unidirectional radiation pattern at all frequencies,
with front to back ratio of 18 dB.
The antenna has a nominal gain of 7 dBi and has a
typical VSWR of 2:1 over most of the frequency range.
The antenna is capable of handling up to 200
Watts of CW power.
The construction of the LPDA’s
for use from 30 MHz is for permanent deployment and
above 100 MHz is for easy deployment and to withstand
the rigors of tactical portable use.
The antenna consists of an aluminum boom and a
set of removable dipole elements of various lengths
which screw into appropriate threaded holes on the boom.
The LPDA’s above
1 GHz are radome covered to protect the dipoles
elements from damage due to its small physical nature.
The LPDA’s can be used in shielded rooms or
extended out door use the antenna can be painted
the aluminum parts are irradiated for corrosion
The antenna mounts directly to
the optional universal joint made of dielectric material
delrin on the support mast, permitting elevation and
polarization adjustment form –90 to + 90 degrees.
The entire antenna assembly requires no tools for
