Multi-band V solid dipole 40-20-15-10m (6m) – V2.0E
PST-1524TV
Assemblyng inst uctions:
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 fo get to lub icate the th ead of steel bolts, if d y may stiff them.
lace 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 traps (10m on the inner side, 15m in the middle and finally 20m trap with the tip of
40m end. Even if traps set is already pre-assembled, the joints inside them have the multi drilling, if
necessary to remove the junction concerned and move to the hole that appears to be most suited to
the best resonance.
Longer antenna lower the resonance, shorter antenna increase the resonance. In both cases will have
effect on the others lower bands. Start the eventual calibration always starting from the highest
frequency (10m - 15m - 20m - 40-).
Any drainage holes present on the traps, at the end of assembly should be down side.
Do not seal t aps o tube joints. Antenna must b eath to p event damages due condensation.

When both half-elements are ready, prepare the center plate and assemble all the parts as in the
photo. The two half-dipoles lower ends must protrude from the insulator of 2.5 cm (1inch).
The terminals of the airpin coil, must enter on the bolts head without strain or deformation and
should be secured with its own washer and nut.
Connect a 1:1 balun to the dipole center (recommended) with two wire jumpers no longer than 8-10
cm (the length affects the resonance of all bands), if you decide not to use the balun, connect
terminals of the coaxial opening it as a V directly to the two bolts. Even in this case to make sure
that the two terminals of the coax does not exceed 10cm. If too long, the antenna will resonate
slightly lower. Seal the coax with good quality sealing glues.
The balun, improves antenna operation, prevent there being return RF currents on the shield of the
coaxial cable that could cause TVI phenomena or other RF interference.
When assembled the antenna must have a 'look like the one pictu ed.

After completing the tune-up, check the tightness of all nuts.
If the V dipole is installed above a HF yagi, it is preferable that it is installed parallel to the yagi
boom and at a vertical distance of at least 1,5-2m.
If installed alone it is preferable that at least 5m from the ground / roof / floor.
In particular/special conditions, the antenna can also be installed as in the photo below.
Specifications:
Bands: 40 - 20 - 15 - 10m
Gain: 0dBd
Max powe : 2Kw pep SSB, 1Kw RTTY-CW or in accordance with balun max power.
Half dipole lenght = about 6m (depend from the tunig set)
Rotating adius = about 4.1m
Wind a ea = about 0.3m2
Mast diamete = 40-50mm
Weight = about 8kg
Max wind = 130Km
Mate ial = Alluminum 6060-T6, SS hardware.
Pe fo mance:
The antenna has sufficient bandwidth to cover the whole segment assigned to each single band with
maximum SWR of 2:1 to extremes, the mean SWR in band center less than 1: 5.
40m in the useful portion is about 120-150Kc.
erformance may vary depending on the environmental conditions in which the antenna is installed.
If you can, do not install it at a height of less than 5m from the roof or ground.

Kit 6m (optional)
The 6m kit must be installed as in the photo below.
