Last night I ran the generator and managed to pick up a signal without
an antenna attached. I tried this once I first purchased it to no avail
and was repeatedly told I'd need an antenna for it to work - but not
only did it broadcast a signal on the target frequency, 144.445, but I
could pick up the signal on over 30 other frequencies, ranging from
144.120 to 145.645 - and the signal was very strong on certain
frequencies.

I thought generators could only send one signal out to a select
frequency, not dozens to dozens of frequencies. And the scanner is
located in the same room as the generator, so atmospheric conditions
between antennas have remained the same ever since I started the
experiments. In addition to that, how could it work without an antenna
attached, since the telescoping antenna has to be measured out the
desired length to transmit at the desired frequency? When I did attach
the antenna the signal was stronger of course, but it still broadcast
at the target frequency (and the other frequencies) no matter what
length I put it at. Any plausible explanations for either occurrence?
