Estimate the maximum distance of your radio link based on frequency, transmitter power, antenna gain, and antenna height. The calculator also considers the optical line-of-sight limit — beyond the horizon, communication is not always possible. Why radio range matters Radio communication is the backbone of countless technologies, from amateur radio and aviation to Wi-Fi, maritime…

Designing an efficient magnetic loop antenna requires precise calculations of loop dimensions, conductor diameter, and tuning capacitor values. This calculator helps you determine the key parameters for building a magnetic loop antenna for HF and VHF bands. Simply enter your desired frequency, loop diameter, and conductor size to get optimal values for inductance, capacitance, and…
