Plan with better context

Plan

Use practical RF planning tools to understand tradeoffs before you buy equipment, route cable, or begin an installation.

Interactive tools

Plan the complete signal path.

Turn real installation choices into useful engineering estimates.

Compare feedline choices, visualize power delivered to the antenna, and model cable, mismatch, and component losses.

Convert RF power units, apply gain or loss, and see how logarithmic dB changes affect absolute power.

Calculate voltage delivered to radio equipment, compare copper wire sizes, and understand wiring loss under load.

Model radio duty cycle, battery endurance, reserve, and seasonal solar recovery for portable or remote stations.

Calculate wavelength, common fractions, dipole dimensions, and defensible antenna construction starting lengths.

Explore how SWR and complex impedance affect reflection, accepted power, return loss, and mismatch loss.

Calculate antenna-feedpoint power, ERP, and EIRP while accounting for loss and direction-dependent antenna gain.

Calculate a first-order curvature-only horizon from antenna height using geometric or standard 4/3-Earth assumptions.
