Tony,
All RF energy presented to the wire is radiated ( disregarding losses
). The radiation pattern will be different at different frequencies (
location of peaks and nulls or the radiated energy changes with
frequency ) and the amount of energy presented to the antenna will
likely change with frequency ( the impedance presented by the antenna to
the RF generator also changes with frequency )

All:
The question below came up in a recent conversation:
If a device that generates RFI at a consistent level across the HF
spectrum were connected to a wire that was 1/2 wavelength at a given
HF frequency, would the level of RFI be noticeably stronger at that
frequency?
The consensus was that it *should* be because the device is generating
RF like any other RF transmitter and the wire being 1/2 wave would act
as a dipole at the resonant frequency.
Sounds plausible, but I have a feeling it's not as simple as that.
