Looks like it's a opened up folded dipole. Commonly refered to as a butterfly antenna. Two of them together with one set turns 90 degrees is called a turnstile or a clover leaf. Typically used as an FM transmitting antenna. Jeff |

sorry about the fuzziness - its up quite high on an old building. I was interested in it especially because of the bespoke iron brackets that hold the iron tube that encases the wire. The tip seems to be quite a small loop.....does the wire running through the pipe also count toward the size of the antenna? And although it would typically be a transmitting antenna could it be a receiving antenna or is it too small a loop....or does the size matter!? |

To me, it looks much more like a UHF communications (business band) antenna. The loop is the active part of the antenna, and appears much too small for a 100 MHz antenna... closer to 450-470 MHz. |
