Is a radio telescope less sensitive on the galactic plane? If so, why?

Mostly wavelength. You have less resolution with longer wavelengths. Radio waves are huge compared to optical wavelengths.Sanjay87 said:So in that case, the answer mist be "yes". But why is it less sensitive? I am a newbie, so my question might sound a little strange.
Thanks,

Radio telescope sensitivity refers to the ability of a radio telescope to detect and measure faint radio signals from space.
Radio telescope sensitivity is typically measured in units of Jansky (Jy), which represents the amount of energy received from a source per unit of time and area. A higher sensitivity means that the telescope is able to detect fainter signals.
There are several factors that can affect the sensitivity of a radio telescope, including its size, design, and location. Larger telescopes generally have higher sensitivity, as they are able to collect more radio waves. The design of the telescope, such as the type of antenna used, can also impact sensitivity. Additionally, the location of the telescope can affect its sensitivity due to factors such as interference from other sources or atmospheric conditions.
Radio telescope sensitivity is important because it allows us to detect and study faint signals from distant objects in space. This can provide valuable insights into the universe, including the formation and evolution of galaxies, the properties of stars and planets, and the presence of potential extraterrestrial life.
There are several ways in which radio telescope sensitivity can be improved. One way is to increase the size of the telescope, which allows it to collect more radio waves. Another way is to use advanced technology, such as more sensitive receivers or advanced signal processing techniques. Additionally, placing the telescope in a remote and radio-quiet location can also improve sensitivity by reducing interference from other sources.
