Antenna Gain Calculator

Use this tool to calculate antenna gain (in dBi) from the antenna factor (in dB/m) and frequency (in MHz), incorporating a 50Ω correction factor of 29.8.

dB/m
MHz
Result: 0 dBi

Formula: G(dBi) = –AF + 20 × log₁₀(f) – 29.8

Where:

  • AF = Antenna Factor in dB/m
  • f = Frequency in MHz
  • 29.8 = Correction factor for 50Ω system

This tool helps with:

  • Calculating antenna gain based on measured antenna factor and frequency.

  • Evaluating antenna performance in RF applications.

  • Verifying antenna characteristics in 50Ω systems.
