Using the Stinger to Mount to a Model 2175 MiniMast
Do not use the stinger to mount the Model 3142D onto a 4-TR tripod.
The stinger mount provides on-axis rotation during 90 ° horizontal or vertical
polarization. The stinger enables you to mount the antenna directly to an
ETS-Lindgren 7-TR Tripod or mast.
Before you begin:
 Install the center rotate boom (part# 108197) for rear-mount
stinger-type antennas onto the 7-TR.
 Attach the included mounting adapter to the Model 3142D as
instructed in Using Included Mounting Adapters on page 22.
 You will need one of the optional mounting knobs described in
7-TR and Mast Mounting Options on page 30. To order
optional mounting hardware, contact the ETS-Lindgren Sales
