How does a wire dipole antenna work when not straight?
I think this could be compared to meandered dipole antenna, a technique commonly found in UHF RFID tag antennas. But here is one article for research of VHF dipole antenna. So, if you keep the length l (dipole length) the same and add meanders, the frequency goes down because the electrical length of the antenna is longer:



In your situation the dipole length is reduced, but the electrical length of the dipole is the same:



Even though the "meanders" are a bit different, I suspect it could be working quite close to the intended frequency.
