4.0 Mounting Information
CAUTION: The Model 3126 antennas are precision
measurement devices. Handle your antenna with care.
The Model 3126 Series Sleeve Dipole must be mounted to a support at the
connector end of the antenna. An ETS-Lindgren mounting kit is recommended to
support the antenna.
Under no circumstances should any mounting structure extend inward more than
1.5 inches (38 mm) past the connector end of the antenna. This area approaches
the radiating element of the antenna and any material in this region will
significantly change the performance of the antenna and affect the accuracy of
the measurement. The mounting structure should have a low dielectric and a
minimum amount of mass in the region of the antenna.
When mounting to an ETS-Lindgren mounting kit:
 The antenna mount consists of a Teflon® sleeve with small clamp
screws to hold the antenna in place.
 Fixed length spacers are then attached to the mounting sleeve to
position it at each test position. For repeatable positioning, the antenna
must be inserted into the sleeve until it bottoms out in the socket, then
the clamp screws should be tightened symmetrically around the
antenna to ensure that the axis of the antenna is along the axis of the
mount.
 Note that an RF cable must be attached to the antenna prior to
inserting it into the mounting socket.
 An optional blind mate socket and adaptor combination is available to
allow attaching the cable to the Teflon socket adapter and sliding the
antenna with blind mate connector adaptor into the RF socket.
