All,

Can someone explain what is going on with this antenna? There are two resonant
points, one at about 4.5 MHz and one at about 6. The first one has a low
impedance and the second one has a high impedance. I actually saw this
phenomenon with a physical antenna being measured with an 8405a but had did not
recall ever hearing it discussed.

Thanks - Dan
