Broadband Hybrid Antennas
30 MHz - 6 GHz



Model JB6 Broadband Hybrid Antenna

Our Broadband Hybrid 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 front of the antenna.  The result is a stronger, more stable feed-point 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.
 

Permanently attached dipole elements
with powdercoat sealant

The low-frequency bowtie elements are swept forward and turned in at the ends to reduce ground plane coupling while maintaining performance.  Each bowtie 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.
