K5HH Ham Radio Calculators

Simple ham radio calculators with shortcode.

I'm creating a series of calculators in service to amateur radio operation.

First is the Dipole length calculator. This calculator is built using the formulas I found at . If you wish, use them for figuring out this math for yourself.

Coming Soon: (In no particular order) * Dipole Inverted V * Wavelength Calculator * Frequency to wavelength * Coax Loss Calculator * Power Calculators - Ohms law E/IR - Power Circle P/IE - Power Factor - * Peak Voltage to RMS * Find Resonant Frequency on RLC Circuit * Find Impedance of Parallel RLC Circuit * Find Q Factor on RLC Circuit * Intermodulation * Induction * Resistance * Capacitance * Impedance * Toroidal Inductor Calculations * Admittance * Frequency Modulation Formulas - Deviation Ratio, Modulation Index, Bandwidth * Line of Sight Calculator * Minimum Discernible Signal (MDS) / Dynamic Range (of a receiver) * Time Constant * Vrms * Peak Envelope Power (PEP) * Antenna efficiency and radiation resistance * Effective Readiated Power * Kirchhoff's Current Law * Operational Amplifier * Impedance Matching * Transformer Calculations * Antenna Gain


The dipole calculator allows your website visitors to find the resonant length of their dipole antennas on the second raise.

*** Disclaimer ***

The K5HH Antenna Calculators are for demonstration purposes only and may not reflect actual numbers for your equipment. I have, in good faith, given my best efforts to provide a calculator that will save ham operators time in setting up their antennas. However, ultimate responsibility for the proper use of your equipment lies with you.
