Hello, I am renovating a condo and found this old Winegard outlet with two screws in one plug area and nothing in the other except the Winegard logo. I think it may be a TV antenna outlet, but wanting to confirm. I found this reddit post from two years ago that has something similar, but nothing definitive in the post.Thanks in advance.

My guess, antenna. Others will confirm or set me straight.

How many of these did you find? I like to take one off of your hands.

On the back of this 300 Ohm twin lead antenna jack I see an impedance matching circuit to bridge to the bus carrying the amplified signal from a community antenna. There's even a little trimming potentiometer (the straight blade screwdriver slot on the front) to balance the dB strength of the signal to the sensitivity of the old tube TV tuner.

That makes sense, since it's a condo.

I am wondering if I take the HDMI cable apart and solder it to this device, will it convert my apple TV's signal to SUHD?

And I can probably get the contacts gold plated and sell it for $$$. :angel::angel:

Not an outlet, it's called a tap. Was used in loop or series wired master antenna systems usually in multi-tenant buildings. RG59 was run from the head end amplifier location through each apartment. Each living room had one of those and they came in several different values of attenuation to maintain a signal level "window" at each tap as the signal became less as you got towards the end of the run. That clamp held the two cables-in from the previous apartment and out to the next apartment. There should be some provision for terminating the center conductors but that thing looks pretty well butchered which was the big problem with a looped system. I hated working on them.

Invariably some tenant would screw with the tap in his wall trying to make his TV work better or something and that would disconnect the cables. When that happens none of the apartments downstream from there on that run would have TV. So I had to figure how the run was installed then go apartment to apartment and check the taps- divide and conquer was the technique. If you could get access half the time the tap was behind some kind of book case or immovable object. Sometimes you would have a good idea where to look by how loudly a tenant refused to let you in.
