External antenna issue / reattach a strand

Hello,

For several days now, I've been experiencing signal issues that come and go completely, lasting quite a long time.
Today, I noticed that one of the elements of the antenna is no longer aligned on its axis and is therefore not parallel to the others.
I haven't looked closely, but the rod itself doesn't seem to be broken, just misaligned. So, it would be the mounting that needs to be changed, repaired, or simply... "realigned"? Anyway... I would like to know:
- if this element (which might move with the wind) can cause this loss of signal?
- if I can put it back in place and reattach it (Is it fastened with screws?)
- and if I were to remove this element, would I receive signals as before, or a little less, or not at all because each element is essential?

I'm asking these questions here because I'd like to know if it's worth climbing on the roof, or if the antenna is dead due to this displaced element that must be moving.
I'd prefer not to call a pro for "nothing."
Thank you in advance for your answers.

    Hello,
    In a Yagi antenna, there are director elements (in front) and reflector elements (at the back) to increase the gain of the antenna.
    Where the waves are collected, it's a specific element where the coaxial cable connects.
    I don't think a director element disrupts your reception; however, the collector element might.
    So go check the connection box, that's maybe where the problem is.

    Listening…

      More exotic, I have at home a signal loss caused by doves holding a conference lined up on my antenna... ;)

    Thank you for replying quickly!

    The problem is that I don't have a way to access the roof (easily and safely).
    I think I'm going to call in a pro.
    Thanks anyway.

      It seems to me that the misaligned strand is the one just before the strand where the cable is connected, so... (?)
      Also, yesterday there was hardly any wind, the signal would disappear for a long time and then reappear for a long time as well, whereas today there is quite a bit of wind, and the signal losses/reappearances are much shorter. This makes me think that this strand (which almost touches the other) could be the cause of the problem.

      If a guiding element comes into contact with the dipole/symmetrizer, it can disrupt the collection of signals...
