Build a Radio Telescope Cost
The first thing to note is that when you buy a ready-made telescope, the price is significantly higher. It’s less expensive for you to construct one. Consider radio telescopes such as Arecibo, which cost hundreds of millions of dollars and are operated by scientists.
If you construct your own radio telescope, you will not spend anything near that amount.
Experts put it down to a couple of hundred bucks to do one for yourself, excluding the cost of the satellite dish.
It’s worth noting that radio telescopes are not the same as optical telescopes. It will be more expensive to build yours up if you use an optical telescope.
But for radio telescopes, it is the other way round.
