I’m not sure how long it will take you to construct your own radio telescope.

That is due to the fact that, like any other job, you must set aside a significant amount of time if you want to succeed. These are some factors that will influence how much time you spend;

  • How sophisticated you want the radio telescope to be
  • How fast and smart you will be at executing every stage of the project

So, depending on the aforementioned variables, making a DIY radio telescope might take various lengths of time for each individual.
