I want to test a couple of antenna designs and compare them to a
dipole antenna.

I am wondering if my idea is a good way to measure gain or loss from
an antenna. Here goes:

Create a place in which to install the test antenna which will be
consistent. For example, 40 foot high between two power poles (no
power lines etc, though.)

Setup a fixed location with a Field Strength Meter (FSM) that has a
fixed antenna for testing at that location.

Hang a dipole (the reference antenna) and transmit a signal that can
be calibrated to a fixed location on the FSM. Then hang the
experimental antenna in place of the dipole. Take the measurements
without changing anything from the rig. Measuring the power output
required to meet the same setting on the FSM as the dipole should give
me a fair idea about the gain or loss from the experimental antenna.

or maybe not.

What am I overlooking?
