It reflects some of radio waves. Also the gaps don't matter too much. That's because of the nature of the radio waves, particularly the wavelengths.
In fact there is a large range of wavelengths.
For the shorter wavelengths a "dish" type receiver is needed, with no gaps.
Chicken wire can be used as the surface of a radio telescope because its mesh structure allows radio waves to pass through with minimal interference, making it an effective reflector for collecting and focusing radio signals. The wire spacing is typically chosen to be smaller than the wavelength of the radio waves being collected, allowing the signals to be reflected and concentrated towards the receiver. Additionally, chicken wire is a cost-effective and lightweight material, making it a practical choice for large-scale radio telescopes.
The mesh of chicken wire is about 1 inch across. Radio waves with a wavelength greater than the size of the holes in the mesh will be reflected, so that a chicken wire dish will reflect the radio energy back to the feed horn at the focus of the dish. But because the air molecules are much smaller than the mesh, the wind blows right through the wire without causing much disturbance.
The speed of light is 186,000 miles per second, or 300,000,000 meters per second. The formula is wavelength * frequency = c, where "c" is the symbol for the speed of light. So this gives you a way to calculate the frequency of the radio waves that will be reflected.
One more point; if you need to reflect higher frequencies, you can do this by making the mesh smaller.

Is a telescope used for weather?
An optical telescope cannot be used during cloudy days. Of course, this assumes that the telescope is located somewhere on the Earth's surface and therefore subject to weather. Since clouds obscure the sky - and any heavenly object otherwise visible - the optical telescope will be unable to see anything. A radio telescope, however, can see through clouds, simply because clouds do not block or cause significant interference to radiowaves reaching the Earth's surface from space.

Is the radio telescope an instrument which measures radiation?
Yes, a radio telescope is an instrument specifically designed to detect and measure radio waves emitted by celestial objects in space. It is used to study and observe radio emissions from various astronomical sources, providing valuable information about the universe.
When was the radio telescope first made?
The first radio telescope was constructed in 1937 by Grote Reber, an American engineer and radio amateur. He built a single-dish radio telescope in his backyard in Wheaton, Illinois, which he used to map the radio waves coming from the Milky Way.
Which of these is used in a radio telescope?
Nothing on that list is used in a radio telescope.

What is radio telescope used for?
Radio telescopes are mainly used for astronomy.
When could a radio telescope and light telescope be used together?

When could a radio telescope and a light telescope be used together?
They usually ARE used together, because astronomers want to see if there is anything visible at the same place as this bright radio source in the sky.
Why can't a radio telescope be used on a cloudy night?
A radio telescope can be used on a cloudy night, because its signal can move through the clouds and rain mostly unaffected and still gather data.
