Determine the electric field intensity at a distance of 10 km from an antenna having a directive gain of 5 dB and radiating a total power of 20 kW.
Added by Daniel P.
Step 1
The directive gain \( G \) in linear scale is given by: \[ G = 10^{(G_{\text{dB}}/10)} \] Given \( G_{\text{dB}} = 5 \), \[ G = 10^{(5/10)} = 10^{0.5} \approx 3.162 \] Show more…
