Best Calculators
Recommended Learning Path
- Convert power units before comparing link budgets.
- Calculate wavelength for antenna dimensions.
- Use free-space path loss for a first-pass propagation estimate.
- Use EIRP only after feed loss and antenna gain are known.

Common Mistakes
- Mixing dB, dBm, dBi, and linear ratios.
- Using free-space path loss as a real terrain or indoor propagation model.
- Ignoring feed-line loss when estimating EIRP.
Limitations and Assumptions
RF outputs are first-pass engineering estimates. Real systems depend on antenna pattern, terrain, polarization, regulations, losses, and measurement conditions.
