JB Series
Broadband EMC Test Antennas
30 MHz - 6 GHz
JB
Series antennas are compact, high-performance instruments designed for
EMC emissions
and immunity testing. The
broadband characteristics of these antennas enable them to operate over a wide
frequency range - a must for automated test environments.
Innovative design and manufacturing techniques result in
long-lasting strength and mechanical integrity. The
result is an electrically stable measuring instrument that maintains
calibration over extended use.
The antenna boom is made from a custom aluminum extrusion that reduces the
number of parts at the nose. The
result is a stronger, more stable feedpoint and excellent
cross-polarization properties. The
unique shape allows for a larger feed cable to be used, which
significantly increases the maximum power rating.
Dipole elements are permanently attached to the boom by an assembly technique that maintains excellent electrical characteristics
for the life of the antenna.
The
low-frequency wings are swept forward and turned in at the ends to reduce
ground plane coupling while maintaining performance.
Each wing is attached with dual compression fittings for true
alignment. A tough powdercoat
finish with UV inhibitors seals the aluminum structure and protects it
from sunlight and moisture.
Mounting
JB Series antennas have a 22 mm diameter stainless steel rear mounting tube.
This configuration enables polarization changes without physical
displacement of the antenna, and minimizes the effect of the RF cable by
keeping it well behind the antenna elements.
The Sunol SNAP! mount provides a secure interface to most antenna
positioning towers. It locks
the antenna in place, prevents unwanted rotation and facilitates rapid
antenna changes.
