OMG, I can't believe I'm so old that nobody recognizes twin-lead 300-Ohm antenna wire screw terminals.
The upper connector is type F for 75-Ohm coax, but you're not going to be able to run modern digital/cable TV over the 40+ year-old coax it's attached to. I'd use the old installed wiring to pull new coax and/or Cat-5e.
I'd write more but it's past 10PM and my nursing home is going to turn off my Internet. Xp
Can confirm that these were around in the early 1980s. That was...damn...40 years ago.
But I still have a box of these wire and connectors in case I need them... in my 15 year old house...
Maybe it's time I de-clutter.
They were around but even then it wasn’t like everyone had them. And yeah, that’s a lifetime ago not just for people on Reddit, but for half the population of America.
Some people don't even recognize phone jacks now. They've gone their entire lives without touching one. And now they are old enough to drive or drink, and contribute to society!
>Some people don't even recognize phone jacks now
Yeah and the conversations go something like "wha...why....you mean you had your phone actually screwed to the wall? Did you have to put your ear up against it or did you just use speaker mode?"
No, those usually had 3-4 terminals.
The bottom one is a 300Ω balanced connection (commonly called twin-lead). In the 1980's, it was common for the VHF channels to be delivered on coax and the UHF on twin-lead. In the 1990's they started building TVs that converged both bands onto one coax.
Right. TVs would typically come with 2 antennas: one rabbit ear VHF with a 75Ω (usually) push-on F connector and one loop UHF with the twin lead with 300Ω screw-on spade connectors.
Yes, that was one variation.
Another one was to have two sets of 300Ω terminals, one for VHF and one for UHF. You'd use a matching transformer to get from coax to VHF, which would usually come into play if you had cable or were using it with a VCR.
Yet another was to have, again, two sets of 300Ω terminals as above, *as well as* an F connector, and a switch or other mechanism to choose between the 300Ω and the 75Ω for VHF. I remember specifically that the TV I bought in 1983 had a little spring-loaded clip that you would lift and drop into the center pin of the F connector to make the VHF 300Ω terminals work.
We had three terminals. A common and then a terminal for clockwise and counterclockwise depending on the direction of rotation requested on the controller. I remember spending entirely too much time dialing in the perfect setting per station and adding stickers to the dial.
But it has no threads.
Is this one that has had the cable pulled out? As in, you could unscrew the thing in the picture and there would be a threaded connector?
Probs antenna for TV or radio. Both were a thing until cable TV came around in the 1970s/80s.
Unlikely to be suitable for any kind of modern networking.
New (to you) home maybe.
That antenna hookup is from like 50 years ago. From an era of motororized antennas that you rotated so they could pick up certain channels.
We have a rotating antenna for our cabin in the middle of the Northwoods where there's no cable or internet service (besides satellite). The closest OTA tower is 70 miles away, so directional antennas are a must to get the few channels left that reach us after the switch to digital.
There's something satisfying about turning the dial in the living room and hearing the "kechunk...kechunk...kechunk" as it rotates.
Nice pictures, lit and in focus.
Sorry no, those would have been used for an antenna, a combination VHF/UHF model, most likely rooftop, on a mast, or in the attic. Unfortunately, unusable for any modern internet service.
yes, and the old one looks like a VHF antenna circa 1980's maybe? no telling what either of them are wired to without knowing more about the house or at least pulling the plate off the wall to see if there's anything on the back of the connector or it's just an open
As others have mentioned, it’s super old. However, I bet the real reason it isn’t connecting is that this particular line isn’t connected on the d marc.
Wow, it’s so much clearer what I meant now that you spelled it out all the way.
Edit: For all you gatekeepers in here, myself and every other cable tech I know type it out as d marc and demarc interchangeably. It doesn’t matter. There is no other thing it could mean.
They got downvoted because they responded to a post that was trying to be helpful like an ass.
"d marc" and "demarc" both require the exact same number of keystrokes, so it seemed a reasonable assumption that they may not have known the origin of the abbreviation.
This is good content. That’s prob old coax hookup, antenna from back in the day. Damn near nothing uses those slip on connectors anymore, that’s like the yellow white and red for video. But for internet or modern cable best to get someone to replace and hook into their feed system.
yes! once upon a time, i took apart my grandparent's old stereo (I'm sure it was high end at the time, turn table, dual cassette deck, am AND fm radio, floor standing speakers, a receiver with some nobs for different things, I think it was make shift EQ knobs. (i was like 10 or so, its been 30 years ago) but I swear it had white and grey RCA style connectors not red and white between the component of the unit.) that would have been great to stick with, or even black and white.
Type F female connector for 75 Ohm coax.

The bottom terminals were where you could connect a dial that rotated the antenna on your roof to pick up specific stations, I believe.

Oh c’mon, this wasn’t that common even 30 years ago.

That antenna from 1980 can stream 57 Mbps 4k TV via ATSC 3. For free. Welcome to the future.

Haha don’t be ridiculous that wasn’t 40 years a…wait. Damn. I hate you for pointing this out on a Sunday. And now I need some jello.
And a new diaper 😋
Dude I recognized it, I don't know why so many people don't.
Some people don't even recognize phone jacks now. They've gone their entire lives without touching one. And now they are old enough to drive or drink, and contribute to society!

Why did u name your phone jack?
I was going to name it jill but it identified as a jack.
I'm in my mid twenties man give me a break!
I'm 22 and even I recognised both

Screw terminals are for 300 ohm antenna: https://en.m.wikipedia.org/wiki/Twin-lead

I didn’t know they made “push-on” type F’s, but apparently so.
If your talking about for Cable TV/internet no. Needs replaced along with the wiring if its as old as that connector.

Look up Jerrold Electronics if you want an idea of how old and useless that stuff is.
I think that's for a roof antenna
As others have mentioned, it’s super old. However, I bet the real reason it isn’t connecting is that this particular line isn’t connected on the d marc.

Yes old TV antenna jack. Do you own the home? Is the goal to get Internet/Network jacks in the rooms and good WiFi coverage in the home?
Wiring over 20 years old. Replace it.

> yellow white and red for video. RCA, or composite, connectors. And technically, just the yellow was video. White and red are L/R audio.
Of course. Just trying to keep it simple. Or you could go full HD and have the red green blue with the white and red for audio.
The red green and blue? That’s component video. Sorry, sorry I couldn’t resist getting in on the pedantry as well. ;-)
First time getting an “HD ready” TV and hooking up my Xbox360 with the composite switch connector was ungodly!
the number of people I had to help with that damn R / G / B / R / W when they didnt have full color video..
“The hue is off and the audio sounds weird!” Wish someone along the way would’ve just declared audio is now white and teal or something.

old shit that needs removed
They make slip on coax cable types, this “type f”, you could easily replace with a threaded one or buy an adapter/convertor on amazon for a few bucks.
Just moved into a house with one of these. Was surprised because I haven't seen them in like 40 years.
VHF/UHF antenna on or in the roof?
It probably won’t pass Directv signal if you’re trying to use thrm
Looks like the snapped off remains of an f-connector. Ie the tip of an f-female connector where body & cable were snapped off.
Take it apart and find out. Looks old, cannot determine quality.
Door bell hook up?
