5. Overview
The UT6 and UT10 towers provide a versatile mount for sensors, antennas, solar panels,
environmental enclosures, radiation shields, and mounting crossarms. The 2m (6 ft) height of the
UT6 and 3m (10 ft) height of the UT10 allows for wind measurements at each height.
The main tower frame (
(p. 7)) is built from 2.5 cm (1 in) OD (outside diameter)
corrosion-resistant aluminum tubing. It includes an adjustable mast, a hinged base, anchor bolts,
lightning rod, ground rod, and cable tie kit.
Enclosures purchased for use with this tower must be ordered with the tower mount option. This
provides the necessary bracketing to mount the enclosure to the tower.
