Vertical HF WARC bands trapped antenna PST-27 / PST-273VC - VF
Assembling instructions:
After unpacking antenna, you will find the main antenna tubes pre-assembled already, following
diameter steps.
Tilting it down, do in the way to have all tubes heads coming out from the main tube.
Assembly them as in the picture below.
Lightly lubricate the threads of all bolts before installing (the steel tends to be nailed very easily).
The fastening of the elements takes place by inserting the bolt from the wider hole side so that the
bolt cylindrical head passing thoroughly sit and and rests on the inner tube as show fig.1.
Tighten the nut. Make sure that all bolt heads are on the same side.
Using the same way, extract and connect all sections, less than the larger diameter that has to be
assemblend before on the antenna base and then proceed to final assembly.
When all diameters are assembled, insert the 12m trap and terminal tip. Traps have two drainage
holes that need to look down.
If you bought the version with 30m, also enter the 17m trap and lock it in the same way.
All the sections of tubing and the tip, have multiple holes that serve to make small tuning touches
on the various bands. Some parts are pre-assembled and pre-calibrated, if needed remove the bolt
and move the tuning point. Calibrate the antenna starting with the highest band and proceed to the
lowest bands. Longer elements lower frequency, shortening elements increase frequency.
