AUTOCOSTRUZIONE DI UNA VERTICALE PER I 6mt  (by TATIANA IK0ALT)

Report di IK0XBX Francesco (Segretario Sezione ARI Perugia)

In questo periodo di COVID19-clausura, la nostra socia Tatiana IK0ALT ha deciso di provare a costruire da sola la sua prima antenna verticale per la banda dei 6 metri. I risultati sono stati eccellenti. Recuperando tutto ciò che aveva disponibile in casa, si è messa all’opera ed in poche ore ha realizzato quella che poi si è dimostrata una buona antenna, una GP per i 6 metri. Seguendo i consigli impartiti da remoto, è anche riuscita ad ottimizzare il ROS in completa autonomia.

Ecco qui la “ricetta” dell’antenna casalinga fatta da Tatiana IK0ALT...

Spellare 5 cm di cavo coassiale e separare la calza come in fotoIK0ALT2.jpg

 

Collegare il filo da 145 cm al centrale del cavo ed i due fili da 150 cm alla calzaIK0ALT3.jpg

 

Lulù verifica se i fili sono serrati bene HIIK0ALT4.jpg

 

Il filo del radiatore viene nastrato sul supporto isolante (… una canna di bambù)IK0ALT5.jpg

 

Le giunte vengono protette con nastro isolante (abbondante)IK0ALT6.jpg

 

Ora la parte più difficile per Tatiana, la saldatura del PL259 sul cavo RG213  ..anche questa è fattaIK0ALT7.jpg

 

Ecco la Ground Plane che svetta fiera in ariaIK0ALT8.jpg

 

Dopo un paio di tentativi l’antenna è accordata perfettamente in bandaIK0ALT9.jpg
