Dual-band V solid dipole 30-40m (6m) – V1.0E
PST-34TV
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 main plate assembly.
Extracting elements from the carton box, you will find the element tubes as 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, if dry may stiff them.
Place the element on a plan, and begin to assembly 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.
Insert the set of coils (30m on the inner side, 20m trap with the tip of 40m end on the outer side).
Some inner ends have more holes, they will help you in tuning antenna on your preferite band section, use
the one in the middle for now.
Start the eventual calibration from the highest frequency (30m) and after the 40m tip end.
Longer antenna arm lower the resonance, shorter antenna arm increase the resonance.
Any drainage holes present on the traps, at the end of assembly should be down side.
Do not seal traps or tube joints. Antenna must breath to prevent damages due condensation.
