Detailed Solution
Download Solution PDF- लघुतरंग रेडिओ म्हणजे 1700 - 30000 kHz (1.7 ते 30 MHz) वारंवारता टप्प्यामधील रेडिओ स्पेक्ट्रमच्या एका भागावरील रेडिओ प्रसारण.
- लहान तरंगलांबी उच्च वारंवारतेशी संबंधित असल्यामुळे, लघुतरंग रेडिओला त्याचे नाव मिळाले कारण त्याची तरंगलांबी सुरुवातीच्या रेडिओ संप्रेषणांमध्ये वापरल्या जाणार्या लांब तरंगलांबीपेक्षा कमी असते.
- अँटेनाची लांबी थेट तरंगलांबीच्या समानुपाती असल्याने, लहान तरंगलांबी म्हणजे अँटेनाची लांबी देखील लहान असते.
- लहान तरंगलांबीसाठी, सामान्यत: मेगाहर्ट्झच्या श्रेणीमध्ये उच्च श्रेणीची वारंवारता आवश्यक असते.
