Antennas

QuinStar Technology's QLA series lens antennas are available with apertures ranging from 3 to 12 inches (76-300 mm) for any frequency in the 18-140 GHz range. These antennas consist of a lens which is fed (illuminated) by a specially-designed feed horn. Read more...

Depending on the type of test that antenna may include factors such as:
• Loss due to mismatch of impedance between the antenna output and transmission line.
• Loss due to attenuation of the transmission line.
• Loss due to VSWR at the and/or the receiver.
• Gain due to a preamplifier located at the antenna. Read more...
