SatRadio vs Radex
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SatRadio
This app provides essential tools for radio and satellite communication engineers. It includes calculators and analysis features for antenna parameters, frequency calculations, link budgets, and modem performance. It also offers miscellaneous utilities for RF engineering tasks.
- Dish antenna analysis (axial ratio, gain, line of sight)
- Frequency calculations (phase noise, doppler, wavelength)
- Radio link analysis (coaxial losses, mismatch losses, EIRP)
- Modem performance metrics (C/N, C/I, PER, BER)
- Miscellaneous RF engineering utilities (dB calculator, converters)

Verdict
The clearest difference is rating: SatRadio at 5.0 against Radex's 2.3. SatRadio also leads on ads (none vs shown) and monetization model (free vs ad-supported). Radex's advantage is update cadence (every 2 months vs every 10 months) and ratings volume (3 vs 1). On price, in-app purchases and device support there is nothing between them.
