noise-reducing antenna system

noise-reducing antenna system

[′nȯiz ri¦düs·iŋ an′ten·ə ‚sis·təm]
(electromagnetism)
Receiving antenna system so designed that only the antenna proper can pick up signals; it is placed high enough to be out of the noise-interference zone, and is connected to the receiver with a shielded cable or twisted transmission line that is incapable of picking up signals.
