That appears to be an over the air TV antenna, looking at it from the back side.

Here is what a typical one would look like from the front side.

Ok thanks guys. Suprising to see a TV antenna like this in an urban area.

Lots of good over the air TV channels. Too bad these style antennas have very poor reception below 470 mHz or TV 24.

The big single ears are for the 170-220Mhz band and the smaller multi-ears for 500-700Mhz.
Most of these antennas have sloping attenuation below 500Mhz but fall quickly above 700Mhz.

When they get below their designed 500Mhz limit the directional properties get less and gets more omni directional but will still have some dB gain, especially if you use a mast head amplifier it will compensate and adapt to the antennas impedance mismatch. I have great success with singleband 500-700Mhz tv antennas at 160Mhz compared to a single 160Mhz dipol. You must twist the tv antenna from it's standard horisontal polarisation to a more apropriate vertical installation.
