Is there a way to broadcast TV cable?

Hi
I was wondering if there was any way to broadcast the analog output from the TV cable so i can receive it with an antenna on my TV.
I have a TV in my room but there isn't any way to put the cable in my room so i was wondering if there was any simple way to do it?
Thanks.

SourceCode,
Probably the easiest way is to build or purchase an RF Modulator, and connect the output to an antenna. There is a do-it-yourself article at:
https://members.tripod.com/~petlibrary/rfmod.htm
There are many sources of commercial modulators. Just search opn "RF Modulator". The modulators accept A/V inputs and provide RF outputs on a 75 Ohm coaxial connection. Most of the commercial modulators have selectable output channels in the UHF band.
The transmitting antenna antenna can be as simple as a set of rabbit ears, to a more expensive directional UHF antenna, available at Radio Shack and other outlets.. Warning: I'm not sure if this is legal.

What do you mean by rabbit ears? How exacly must i connect the cables to make a simple antenna?
And do you think i will get signal to about 5-10m away without using any kind of amplification?
Thanks alot

Re: Broadcast TV cable?

"Rabbit Ears" is a term for a very simple indoor TV receiving antenna that forms a V shaped structure. It's not an efficient antenna, but it may be good enough for your application. The modulator has a 75 Ohm coaxial type connector for its output. You simply connect a 75 Ohm cable from this connector to the antenna. Most "rabbit ear" type antennas are supplied with balanced 300 Ohm inputs intended for 300 Ohm twin lead cable. You will need to purchase a balun to convert the 75 Ohm unbalanced output of the modulator to the 300 Ohm balanced input that the antenna requires. Baluns are sometimes sold under the name "75 Ohm to 300 Ohm Converter" or "300 Ohm to 75 Ohm Converter". Virtually every consumer electronics store has baluns and rabbit ear antennas. They are very inexpensive.
.
I suspect that the modulator will have enought output to use with no additional amplification. If not, you can use an inexpensive booster, also available at any consumer electronics store.
.
Keep in mind that any receiving antenna can be used as a low power transmitting antenna. The directional properties when used as a transmitting antenna will be identical to the directional properties when used as a receiving antenna.

Broadcast TV cable?

Woah you lost me, but i will go take a look at my local electronic store.
You really helped me, Thanks!

So just to be sure, i could just plug one antenna on the cable output, and one on the antenna input from my TV, and it should work?

Btw, would it be illegal to use it inside your house? Im not gonna broadcast my cable to the entire city!

Re: Broadcast TV cable?

Source Code,
Yes, your 2nd paragraph is correct. Regarding the legality, I know that there are restrictions on the power of the transmitter that is allowed for home use, but I don't know what the legal limits are. In any case, the power available from your cable or modulator (if you use one) is very small. I may have misled you on the necessity of using a modulator. If your 2nd TV is cable-ready, you don't need to use one. If not, the mudulator will convert the cable channels to a channel in the UHF band.
