Can someone help me figure out what kind of antennas these are? I found them in a storage locker full of commercial radio gear
Measure the length of the antenna and that can help with a ball park idea of the frequency range.
For reference note the length and frequency coverage of this antenna:

But you have no idea if it is a 1/4 wave or a 1/2 wave or a collinear type or whatever. Measuring will not do any good unless you already know what type of antenna it is such as folded dipole or 1/4 wave etc. Some 2m antennas are 16 FEET tall while some are 19 INCHES tall.
Agreed there can be different types of antennas.
My thought was that with a rough measurement in conjunction with a picture it would also potentially help someone that recognized the antenna offer better feedback
