Portable Mobile Telescopic Masts And Telescopic Antenna Telescopic
Mast
Manual telescopic mast installation instructions:
1. Vertical use: manual telescopic mast can be installed on the
ground, as well as on the vehicle. But no matter where it is
installed, make sure it stays perpendicular to the ground. If the
manual telescopic mast is tilted, it will affect the effect of the
manual telescopic mast rising and descending. If the manual
telescopic mast is heavily tilted or tilted for a long time, it
will cause damage and danger to the manual telescopic mast.
2. Guy wire fixed: manual telescopic mast needs to be installed in
a fixed object, and could not shake, such as walls, car body,
foundation piles and so on. The fixed points should be two points
at least, one of them in the manual telescopic mast, the distance
between the two points is greater than 2/3 height of the manual
telescopic mast. The connection should be firm and reliable.
