HamTenna is an antenna workbench for ham radio operators. Build wire antennas in a real 3D viewport, then solve them with a Method of Moments engine cross-checked against NEC-2 and the textbooks (Balanis, Kraus, ARRL Antenna Handbook). Read feed impedance, gain, radiation patterns, SWR and impedance sweeps straight from the solved currents, not a lookup table. Free space, perfect ground, or real soil models. Everything runs on your device: no account, no network, no tracking.
