Some active whip antennas with FET inputs, like the Rohde & Schwarz HE010, do not have a FET gate bias adjustment or any other method of adjusting its IIP2; a two resistor voltage divider is used to fix the FET gate bias at about half the DC drain voltage and the IIP2 is whatever that gives you. The same is true of the pa0rdt Mini Whip.

The problem is that the PA0RDT Mini-Whip is an active antenna, and picks up a lot of noise from the environment, which in my case is my lab. The Wellbrook Loop Antenna also has active amplification but picks up more of the magnetic field opposed to the electric, so it’s not as sensitive to noise sources you usually find in homes.

A cheap mini-whip antenna in those circumstances is unlikely to be satisfactory in any configuration, in my opinion. Assuming that you're only trying to receive, in your shoes I think I might try attaching a wire to a guyed fiberglass pole with some sort of air-wound inductor at the bottom, with several long radials running along the ground.
