As far as “what’s it for?”: All antennas are designed to receive and/or transmit on some range of frequencies. In this case, the antenna is designed to operate on the frequencies the FCC has assigned to the amateur radio service.

A full list of amateur frequencies is here: (But that page includes frequencies the pictured antenna does not cover.)
