I just received my RCA caps, and they look great. However, I do not know which part to solder. I already bought the Coax Stripper for an RG6 coax. I just examined my RG6 cable, and noticed that there are several layers. From the outer
layer:
1. White rubber coating/jacket
2. Strands/Braided of Silver wire
3. Foil Wrap
4. Strands of more Silver Wire
5. Foil Wrap again
6. Foam thing
7. The Thin Copper Pole

I just want to know which layer/layers do I solder onto my RCA plug. By the way, this RG6 was pre-wired by my builder. I am new to this as you can tell haha.

Here is a picture of my RCA cap/plug I purchased.

It looks like I can't post the picture yet since this is my first thread and post. I'll post it later?


Or if anyone can describe which to solder where, that owuld be great!

Pictures, numerical order.

Coax - crimp

Coax - solder

Thanks for that link!!
So Basically, if I wanted to solder, I just have to solder the copper core to the gold pin of the RCA? and strip back the other (foil/braided silver wire) stuff, besides the Foam and the Copper core? I was under the impression that I had to solder the Braided silver wire as well.

Also, do I need to put that clear plastic thing? is there an alternative to that? electrical tape or something?

More info would be much appreciated! :)

Oh yah, so is that Foam layer "Ground"? if not, which is Ground, because I think I was told I have to solder the ground part, as well as the copper tip. Is this correct in any way? :confused:


Update:

The person who sold me the RCA caps, said I need to solder the "ground" to the base of the RCA cap. Now, from my layers, which is the ground? :confused: :confused:

Is it the braided silver wires? if so, which one? the one next to the outter jacket? or the inner one?

Need some more help! I'm going to be getting my Subwoofer soon. I wish the builder just capped it with an RCA :(

Now I was told to solder the Braided wires. Is this correct? I would solder braid to the "gold dip" below the gold tip and solder the copper conductor on the tip of the RCA cap?

I'm going to start to solder tonight or tomorrow, so any more help would be very helpful!

Thanks :)

4. Strands of more Silver Wire

6. Foam thing
7. The Thin Copper Pole


Who makes this esoteric cable? You don't need a multi-layered cable like this. Something
simple like this works fine even for high end digital transmission.

1. Strands/Braided wire
2. Foil Wrap
3. Foam thing
4. The Thin Copper Pole

The cable pics I linked are Belden 1694A, a high grade cable great for digital transmission
and it's not esoteric like the one you have. Since you have that cable, I'd just connected all
the braids together to form one connection unless you have other esoteric plans.
If this cable is to send an analog subwoofer signal then you definetely don't need exotic
cables, not even Belden 1694A, you can use much cheaper alternatives like Belden 8760;
http://home.pacbell.net/lordpk/cable...en_8760_Cable/

The RCA solder pics I linked, the RCA's have a screw to secure the braid {ground path},
and there was no easy way to solder that braid to the RCA housing, a preferred method,
therefore I didn't really like that RCA connector I bought, I liked the Coax RCA solution
better, but if you have a method to solder the braid, then do it. Don't let any braid or
shield wires touch the center signal conductor as it will cause a short. Use whatever
means to isolate it, even electrical tape is fine.

THANK YOU for the reply!!!!

Yah, I'm not sure who created that cable. It came with the house as a pre-wire option. So I have to screw in the screw onto the braid. I thought the Screw was to screw onto the jacket so the cable will not budge. It's a good thing you told me!!

Yah, I purchased a very similar RCA cap to the pictures you sent me on that link. so that is of great help by itself. I just wanted to make sure, because as you said, my cable is esoteric haha

Oh wait, according to your pictures however, it looks like the screw is hitting the black jacket, which has some strands/braid folded on it?

Now, do I fold all my Braids back over the jacket and screw in the screw onto that? or not.

thanks again for your help. I will solder this stuff tomorrow, I want to get your feedback once more!
THANKS!

Edit/Update:

Sorry for being such a Newb haha :p

Have you considered crimping on standard f-style connectors to the RG-6 and then using an adapter (F to RCA)?

Seems like the EASIEST way to me. :)

Rule #1
The idea is to make good electrical contact, so whatever works. Soldering is
the best way to ensure a good electrical contact. The second method is to
use the crimp style connectors- but a good crimping tool ain't cheap. I've seen
screw-on type of connectors where you twist {screw them on} the coax, I think
Radio Shack has those, but those ones don't last very long because it's neither
soldered or properly crimped.

Rule #2
Don't short the braid to center conductor.

Rule #3
Don't yank on the cable to when disconnecting it, the connector may break off. lol

Yah, Crimping would probably the easiest way, but not the cheapest. and I like the challenge haha. I hope I dont screw up.


Thanks for all your help thylantyr.
