As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
radio telescope detects radio waves and a light telescope views light waves.
Radio Telescope Arrays
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths

Stockert Radio Telescope was created in 1956.
Radio telescope can "see" radio spectrum events and locations in the universe.

The most powerfull type of telescope is the Radio telescope. Radio waves travel much further than light waves.
To make a tv telescope
The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.
