4.0 Mounting the Model 3164 Series
The Model 3164 Series Open-Boundary Quad-Ridge Horns are designed to
mount directly on the shield line of a shielded anechoic chamber. Mounting
features include:
• Chamber wall mounting holes—
Equidistant holes around the
circumference of the adapter plate
accept 1/4–20 thread screws and
nuts for mounting to a chamber
wall. The Model 3164-06 provides
twelve holes, and the Model
3164-07 provides eight.
• Easy access to SMA connectors— The circular mounting plate
provides the primary interface to the shielded enclosure mount panel.
By fastening the mounting plate to the shielded enclosure, the two
SMA connectors are on the outside of the enclosure, providing easy
access. This also puts the cables outside of the enclosure, which
reduces the effect of the cables on the measurement.
• Security of shielding integrity— The back end of the antenna is
machined of a single aluminum block, so the shielding effectiveness of
the enclosure is not compromised by installation. This unique feature
eliminates the need for a transmit antenna positioning device or a walk
path inside the shielded anechoic chamber, both of which could
present unwanted reflections of shielded anechoic chambers when
installed improperly.
• Maximize test range distance— The integrated mount fixture allows
maximizing of the test range distance for a shielded anechoic chamber
of defined dimensions.
