lifespan of satellite dish

Question

Hello,
I wanted to know, if possible, the average lifespan of a TV satellite dish.
Mine is from 2002 and I’m wondering if I should replace it entirely since I have to move it; it’s blocked by trees, hence no reception.

Without this reception issue, it still works well when there isn’t any foliage (winter, early spring).

Thank you for your comments.

And if you have to change it, while you're at it, take a resin parabola that won't rust...  -- I call a spade a spade...

what has a lifespan is rather the head. The dish must be cleared in the direction of the satellite.

Hello  Are you saying we just need to change the head?

It depends if the dish is rusty and the screws too because it's the dish that sends the signal to the receiver, which can cause poor or no reception, so it might be better to install a new one.

Hello
according to your advice I had the satellite dish changed and everything works well.
Before, only channel 5 of France Télévisions was "somewhat" working.
The technician explained this to me in a visual way:

Each channel has its own wave that hits a specific point of the satellite dish.
Probably the wave from channel 5 was hitting a privileged point of the satellite dish.

I think he wanted to talk about frequency, well, I didn't understand everything!

Everyone knows, for example, that France 5 is in the same multiplex (R1 or GR 1) as France 2, 3, LCP, France 0.....

Yes, but that doesn't tell me anything.
I wanted to understand, if possible, this story:
that a wave hits a specific point of the parabola

Unless it's too theoretical!

Hello Andy
Now it's clear to me.

however, it is possible that the head preferentially receives a certain frequency

and maybe a quality (more expensive) head preferentially receives multiple frequencies.
