Program models a 1/4-wave vertical and 1/2-wave dipole antenna to
demonstrate how input impedance and SWR behave in the vicinity of resonance.

Transmission line Zo can be varied to match the resonant antenna. Frequency
can then be varied to observe how SWR varies over the band.

Download program R_X_SWR in a few seconds and run immediately.

No increase in price.
