Mounting
All items mentioned in the Mounting section are options. Please
contact ETS-Lindgren Customer Service for additional information.
The Model 3127 Resonant Loop Antennas should 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 3.81cm (1.5 inch) 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 are 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.
