7-TR WITH P NEUMATIC P OLARIZATION
Specify the type of boom required when ordering a 7-TR with manual
or pneumatic polarization; a boom is not included. For a list of
available booms, see Boom Options on page 11.
The 7-TR with pneumatic
polarization enables
remote rotation of an
antenna between
horizontal and vertical
positions while maintaining
a constant rotational axis
for the centerline of the
antenna. A coax cable
guide at one end minimizes
stress on cables during
use.
