SPECIFICATIONS

SAS-571

Description

The SAS-571 Double Ridge

Guide   Horn   Antenna   is   a
linearly   polarized   broadband

antenna covering the frequency range of 1 GHz to 18 GHz. With High gain, low
VSWR,   an   input   power   handling   capability   of   300   watts   CW   makes   this   horn
antenna an excellent choice for both immunity and emissions testing. The SAS-
571 Double Ridge Guide Horn Antenna is a must have for testing above 1 GHz.
This antenna is precision machined from aluminum and may be mounted either
horizontal   or  vertical  polarization.   A  1,   3   and   10  meter   individual   calibration   is
included with purchase.
