భావన:
రేడియేషన్ కోణం అనేది క్షితిజ సమాంతర యాంటెన్నా కోసం అత్యల్ప లోబ్ 'θ' యొక్క ఎలివేషన్ కోణం \(\theta = {\sin ^{ - 1}}\left( {\frac{{0.25}}{h}} \right)\) ద్వారా తరంగదైర్ఘ్యం 'h' పరంగా యాంటెన్నా యొక్క ఎత్తుకు సంబంధించినది.
అందువల్ల ఎత్తు పెరుగుదలతో, సైన్ ఇన్వర్స్ ఫంక్షన్లో విలువ తగ్గుతుంది కాబట్టి θ విలువ తగ్గుతుంది.
