Effective radiated power (ERP) is defined as:
ERP = G ⋅ Pt watts
Where, G = Gain of the Antenna
Pt = transmitted power
Calculation:
Given that, G = 30 dB and Pt = 10 W
Since, G(in dB) = 10 log10 (G)
30 = 10 log10 (G)
3 = log10 (G)
∴ G = 103 = 1000
∴ ERP = G ⋅ Pt
= 1000 × 10
= 10,000 wattsLast updated on May 30, 2025
