It’s an amateur (“ham”) radio antenna. Most likely this SteppIR model (they have a very distinctive design): https://consumer.steppir.com/shop/horizontal-antennas/4-element-antenna-products/db36-yagi-antenna-80m-6m-package/
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: http://www.arrl.org/frequency-allocations (But that page includes frequencies the pictured antenna does not cover.)
