This is A simple RF adapter. It can be used for old video game systems and, basically anything that has an RF output. If its made properly you can get no interference on the channel. It can also be made out of stuff you and everyone else probably already has in there junk drawer! For novice makers, it should take about 7 minutes. This adapter turns an RF output into a coax output, just so you may know. Let's get started.
Step 1: About RF.
If you were born after 1990, you probably don't even know what RF is. RF is basically an old-fashioned way of connecting your video game console and/or VCR to A TV, if you know what A VCR is. Above is a picture of A RF output on the Atari 2600 Jr. There is not much more to say about it besides that. Let's get making!
Step 2: What You Will Need
To make this RF adapter, you will need the following: 1. An RCA cable. The length is up to you. 2. A coaxial cable. 3. A female to female RCA adapter, which is 75¢ on eBay. 4. electrical tape. 5. A knife. 6. Needle nose pliers. That's about it on our shopping list. Let get to it!
Step 3: Time to Assemble
Repeat the following steps.
1. Take coaxial cable and cut at least 3" away from the screw on connector.
2. Take RCA cable (There all the same on the inside) and do the same as on the coaxial cable. You can make this as long as you want to.
3. Strip both wires 1" from the cut point. On both cables under the first layer of plastic, there are usually silver wires although colors may vary. these are the negative wires. the wire which is usually under a white coating of plastic (This is the positive wire and the plastic is to keep the positive and negative wires separate) strip off that plastic between the two wires and keep the wires separate. For more details on these wires, feel free to ask any questions or use A search engine.
4. Use the needle nose pliers to make A u in the coaxial cable positive wire. (picture 6).
5. twist the positive wires of both cables together. (picture 7).
6. Pull the negative wires back so that they do not come in contact with the positive wires. Afterwards, take about 2" of electrical tape and tape around the positive wires. (pictures 8 and 9).
7. Now once the positive wires are taped up, pull the negative wires over the electrical tape covering the positive wires so that the negative wires of both cables are touching. Afterwards tape around the negative wires like you did for the positive wires an tape around these until you think this cable you just made won't pull apart any time soon. (pictures 10, 11 and 12).
Step 4: Your Done!
All you need to do is use that female to female RCA adapter when your playing Atari, and just take it off if you want to play the NES. Now you can feel free to play Space Invaders (I am not referring to siblings) without some huge box hanging out of the back of your TV. I mean it! Space Invaders with no siblings...er strings attached!
