Wideband Horns
Typical 3D radiation pattern
The SATIMO wideband horns
have been selected as high
reliability reference antennas
in international measurement
facility comparison campaigns.
REFERENCE ANTENNAS
> Main use:
• Gain reference
• Wideband probes for far-fi eld test ranges
• Refl ector feeds for high gain applications
> Delivered documents:
• Typical performance data (TYMEDATM)
Measured return loss data
•
> Surface treatment:
• Alodine 1200 according to MIL-C 5541E class 3
• Blue paint
> Related services:
• Calibration and maintenance
• Customization
➊ TECHNICAL PERFORMANCE
• Stable gain with frequency
• Linear polarized with high polarization purity
• Low return loss / VSWR
• Wide bandwidth
➋ DESIGN
• The horn maintains a well defi ned smooth
radiation pattern in the direction of the boresight
axis throughout the operational bandwidth
• The unique design prevents excitation
of unwanted higher order modes in the aperture
• Lightweight for easy handling
➌ REPEATABILITY
• Stiff and robust mechanical design
• Standard SATIMO circular interface for precision
centering
• Precision pin for accurate polarization alignment
• Precision machined
• High reliability connector

Wideband horn
SMART POSITIONING
The circular interface allows the user
“W”
“H”
to position and center the antenna
with very high accuracy. The horn
is fastened to the customer’s
mounting support by four screws
“L”
and the alignment is determined
by a precision pin in the mechanical
interface plate.
