Only going from a guess about lengths in the picture the thing could probably be used on frequencies in the 90 Mhz range to maybe the 50 Mhz range. If it will extend to something like 16 - 20 feet, then that freq. range possibilities would extend down into the 20 - 30 Mhz range. Boy, is that a rough guess!
Could it be used for CB? With that variable length, and the impedance matching 'ring', that's a definite 'maybe'. Which says absolutely nothing about how 'well' it might work.
One thing you might do is examine the elements for marks where it could have been used to adjust length. You might get some kind of indication as to extended length.
It does appear to be well constructed. No razor sharp points/edges, which is nice. After that, your guess is just as good as mine.
