## Description

A simple RF Tool to calculate:
- Free Space loss
- RSSI
- Pathloss
- EIRP

for a given RF link taking as inputs:

- Frequency (GHz)
- Distance (km or mi)
- Tx and Rx Antenna gains
- Rx Sensitivity
- Tx Power

This App should be periodically updated to incorporate additional useful RF and Telecom engineering formulas.
