“The feedline to an antenna will perform better if the antenna has the same impedance. Jim Heath W6LG uses the RigExpert AA-2000 to measure a small dipole’s resonant frequency which is not the same frequency as the lowest SWR. The resonant frequency of an antenna is often not the same as the frequency with the lowest SWR.”
