PRO.SIS.TEL. PST-DDR5 Assembly Instructions Manual

PST-DDR5 - 6 - 7
Assemblyng instructions:
The antenna can be assembled in different ways:
Assemble it on two sawhorses and then carry it on the mast or pre-assemble the elements and then complete
the assembly on the mast.
In both cases it is preferable to prepare before the elements and then the boom. If possible, given the
delicacy, the supply lines it is preferable that they are installed with the antenna on the mast already.
Extracting elements from the carton, you will find the element tubes pre-assembled elements, in a telescopic
set. Tilt the tube set, make sure that all heads of each diameter escape from the main pipe. Do not forget to
lubricate the thread of steel bolts, left to dry may stiff them.
Place the element on a plan, and begin to asembly the smaller diameter,
Align the hole of the inner tube with hole of the outer tube. The fastening of the elements takes place by
inserting the bolt from the larger hole so that the cylindrical bolt head pass thoroughly and rests on the inner
tube fig.2. Some sections are multi-perforated to facilitate the adjustment, always start from the center hole,
and then shorten or lengthen it if antenna is too long or too short.
Using the same technique, extract and splicing all sections and traps.
Tighten the nut. Make sure that all bolts heads are on the same side.
The central element of the Director and radiator are pre-assembled on the boom mounting plate already. It
will then be attached to the boom with square U bolt.
The traps are equipped with drainage holes that need to be down.
When the two half-elements are ready, prepare the two radiators center plate as in the photo and drawing.
