The wings are the dipole antenna to receive VHF, channels 2 to 13. Both the antenna elements inside the plastic housing receive UHF signals, channels 14 to 36.
You should sweep it with a VNA and see how it behaves? If the relay bypasses the pre-amp when its not powered, you ought to be able to sample its characteristics.
“maybe these wings make it more omnidirectional” 😂

You could hook it up the same way as the ufo one and compare the receive power.
85 miles. sure if its 180 ft in the air. The dipole is the high vhf.
very unusual and very interesting. I haven't seen that type before.

Doesn't look like a filter. Looks like a balun found in many TV antennas.
