Default Dummy Load Antenna

Has anyone ever tried putting a dipole antenna up with the center
insulator being a high power 50 ohm dummy load,then connecting the
dipole elements across the dummy load.This would always keep a
suitable match at 50 ohms and satisfy the transceiver.Would most of
the power go to the dummy load and not the elements and wouldn't
radiate.In thinking about this it all logically makes sense the load
would really never change or would it have some reactance with the
dipole elements. Thanx All

Firstly, your proposal does not produce a 50 ohms antenna at all
frequencies. Your circuit analysis skills are lacking.

Various antennas include a resistance somewhere, and although it means
loss, it limits the feedline VSWR excursions with frequency and the loss in
the resistor may be more than offset by the reduction of feedline loss at
some frequencies.
