Lessee: 23 feet, say 7 meters is a quarter wave
so a wavelength is 28 meters.
300/28 = 10.7 MHz or a little lower....
The wire in a glass whip can break.
Checking it for resonance would eliminate this possibility.

The wire in the whip isn't a straight piece of wire. It's coiled
around a form to form a continuously-loaded shortened whip. The
electrical length of it is considerably longer than 23'. It'll
resonate lower than 10 Mhz somewhere......
Nope, it is just a straight piece of wire. No coils at all. Unless it
is one of the old antennas for 2 mhz only.
With a coil in them they will not work above 4 mhz. Only a small part
of the antenna would be effective on the higher frequencies.
