I moved on the balcony and using the ceiling hook I hanged the full antenna. Two ropes were holding it pseudo-horizontally; half antenna was outside, half inside...
Altought not perfect, the resonance moved up into HAM 2m band:
Hopefully in more clear space the impedance will get even closer to 50 ohm. In the evening I tightened nuts and bolts of each element.
Left to be done:
- mark elements and respective boom position, probably with colored PVC tape for fast visual recognition
- attach the BNC connector to the dipole box
- find out how to connect the boom to a fiberglass mast
