ETS-Lindgren 3164-10 Open Boundary Quad-Ridged Horn - Manual (Page 10)

10 Introduction www.ets-lindgren.com
Testing of the Model 3164 Series shows that the isolation level between the two
orthogonal test ports is better than 24 dB in the specified operating frequency
range. The port isolation is the limiting factor in the cross-polarization levels of
the antenna.
The Model 3164 Series antennas are designed to operate from 300 MHz to
18 GHz in a free-space environment. When the antenna is installed in a
rectangular shielded anechoic chamber, the equipment under test must be at a
test distance meeting the far field requirements to operate either antenna within
the full frequency range.
In a quasi-free space test environment such as a tapered anechoic chamber, the
Model 3164 Series antennas are ideal plane-wave transmit and receive
antennas. They are ideal for use in a taper chamber over the entire range,
provided it is repositioned inside the taper to obtain the optimum illumination.
The Model 3164 Series antennas ship with standard mounting hardware. For the
variety of mounting options available for each antenna, see Mounting Instructions
on page 25.
Model 3164-05
The 3164-05 is the smallest of the Model 3164 Series, with
an operating range of 2 GHz to 18 GHz.
The 3164-05 is designed for the antenna measurement in
the MW range, and covers the S, C, X, and Ku bands. It was
designed as a receive antenna, but can be used as a low
power radiator with a maximum continuous power handling
capability of 10 W.
