Depending on your OTA antenna design it might be close. I've built several simple loop antennas over the years for picking up FM and they work quite well. The best solution I've come up with used ~1/4" copper tubing with the matching transformer wires screwed into the ends of the tubing. Loop antenna gain is all about encircled area and having a perimeter that is a fraction of the median target wavelength.
Loop antennas are a bit directional though. They have a gain pattern that looks like an 8 when looking down on them. They have a lot of gain normal to the loop and very little gain parallel to the loop.
