I am enjoying this thread and learning a lot. Can you describe how you
would measure the radiation resistance for two 630m antennas; the first
being a short (400') loaded, center fed dipole, and the 2nd antenna
being a conventional, short base loaded monopole with capacity hats fed
against a small radial field? TU es 73
