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 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 pictured.
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.
(Balun and eyelet ends are optionals not included in the antenna parts)
Balun or coax choke do not improve antenna performance, but reduce the RF presence on the coax shield reducing the risk of TVI or other RF noise on electronic devices.
