Hmm, Ok then maybe i'm not asking the correct question. I was thinking if
there is a way to make a screwdriver antenna appear or act like a "loop"
style antenna in which the radiator is connected to ground creating a "dc
short"

At my previous residense I had a large loop antenna and i was always
impressed with how low of noise level it had in comparison to other
antennas.


Hi Jeremy,

A large loop? From the radiator out and back to the ground mount?
Most short loops need capacitance (kinda the inverse of short
monopoles need inductance - hence the utility of screwdrivers). For a
larger loop, you may need additional components (dare I suggest
capacitors again?); but if you didn't give it a try, then you might
lose your amateur status; any way, you can attach a cap anywhere for
a quick-see.
