Old tv to new tv with old flat wire

[Teeton]

I have a old 1983 motorhome that has a old tv antenna that has a flat wire that has 2 wires inside. The antenna that you screw up works well, but I got a new flat screen tv and it only has a place for the screw in antenna wire. Can you up date the wire on the antenna to the new round wire that screws to the back of the tv or do they make a adapter to hook the old flat wire to new tv's.. Thanks Ed

No, you can not Fook up 200 ohm flat antenna wire to a 72 ohm coax! You need a transformer, Radio Shack use to carry them.

That has to be the funniest typo I have seen in a long time. Made my evening! :B

Make that 300 Ohm balun, as a few folks had previously suggested.

Whew, glad that's over,....or hopefully is !
The very first (....and last couple) post was CORRECT. If you don't know, why answer ??
Yep, I played w/ all this stuff 50+ yrs ago.

X2, this is what you need, a balun.

There is an adapter with built-in transformer that plugs into the 'screw-in' cable connector and has screw terminals for the 300 Ohm twin lead. No additional cable or soldering is required. It is pictured in the first response to your post by agesilaus and is the second item down in the Amazon photo.

If the "screw up" antenna is a Winegard like this, or similar

Then it should be equipped to run the coaxial 75-ohm cable ("screw in" as you call it) and you can run the modern, more efficient, cable from the antenna to your new TV.
Take a good look at the diagram Roy Ken posted above. For the Winegard and other "RV" antennas to work, they need power from that plate with the pushbutton switch on it. Do you have one of those? Does the ON light glow when the switch is pushed IN?

If the antenna and wiring are good, it will work. It may not be as effective as a modern new antenna (i.e. have less range in poor conditions).

The RF signals for digital TVs are in the same frequency bands as they were for analog TV. The antenna system doesn't care at all what sort of information is in the carrier signal or how it is encoded. At that level, it's all just analog RF.

With the right adapters and whatnot, a TV antenna works very nicely for FM radio reception, too. The FM band is literally right in the middle of the VHF television band.

They make the adaptor that hooks the old antenna to the newer TV. You don't need to get and cut wires on one like shown above that hooks a newer antenna to an older TV.

Just cut off the spade lugs and twist the two 300 ohm cable leadsfrom the antenna to this adapter. Best to solder them in place...

If it were me I would replace the old trailer antenna with one of the more modern WINEGARD BATWING antennas that has an built-in booster amp and use one of the WINGARD WALL PANELs to power it up... This is what most of use for Over-The-Air Digital TV reception on the RV's... This setup uses the standard RG cables...

I remember having a connector that had two flat wires with U shaped ends connected to some kind of a round attachment.
