That's a pretty good source, but I think the lack of the lock connector makes for a real bitch in practice.. I do have one of those docks here and it did cross my mind up until that realization.

Yep, two layers of different inner diameter heatshrink, about two mm in length are inside, holding both the antenna and audio connectors in there.

Quote:
From the photos It looks like there are small square pads where you solder these connection too. It's hard to see where to connect the wires from the RF connector Tip and ground.

In your post you say:

"there are four connections going on here. You have Left, Right, Coax Tip, Coax Ground. There also are what looks like two resistors on the board, but it's very difficult to follow what they tie into"

Can you be a little more specific or will it be apparant once I open it up where these connections go?
If you do it right, it should be apparent. If I were doing it again, I would just cleanly slice the sheath lengthwise, perpendicular to the circuit about a 1/8" from the circuit. This will cut through your wiring, but you pretty much aren't going to be able to save it anyway. After you do that, I think you can pull the remaining sheath away from the circuit carefully enough to see where the wires are soldered to the circuit. Also, one other note, the coax ground is the common ground for the audio as well.

DaJoker, Thanks for your help on this. It looks like a fun project!

No problem.

What I was wondering is that is you used the type of connectors that are pictured earlier in this post by me and just crimp a FSMB onto the wire and plug a standard antenna into that. Do you think that it would still power the antenna? I would think so because if it is recognizing the headphones are connected to the stiletto and providing power to the antenna, then you would think that it would still power to the fsmb connector to whichever antenna you elect to connect.
Jason,

I'm thinking of getting both a male and female SMB Crimp Connector to shorten a Dot Micro or Home Antenna Cable and use the other to make the connector for my radio. I currently don't have the connectors or the crimp tool but will look for those this week. From what has been said, it seems that the power to the antenna is not the issue, it seems that it's those 2K resistors that are used to "Turn Off" the internal antenna and switch to the external one. If DaJoker can get his Home antenna to work, I don't see why the Dot Micro car antenna will not work either. I'm not an expert here so I guess the proof will be in the results.

Actually, I'm not sure what type of coax is used in these antennas. I don't think it is 75ohm. I know it's too thin to be RG6, It's some type of "Micro Coax" that but I'm not sure what the name of it is. I was going to just use some of the existing wire off an antenna I already have.

I'm sure it will end up costing a hundred bucks to buy the tool and the connectors. No one said all this fun is cheap. I'm always a sucker for a new tool. Anyway, once I have the tool, I will be able to shorten up some of the cables I already have. I'll just put it with all my other punch down tools and crimpers for RJ45's RJ11's RG6 ect. ect. When I retire, I'll be able to go to work as a field service technican. I'll allready have all the tools necessary.

BTW. If anyone knows a source for a SMB Crimp tool and a place for the male and female connectors let me know. I looked on ebay and I saw Antenna World www.antennaworld.com has the connectors. I'm sure there are lots of places on the web. But if anyone has good experience with some vendor or good prices please let me know. I'm sure radio shack is not going to have them.

If I end up doing the project, I'll be sure to post it.

The coax is RG58 as I recall, which typically is 50ohm.

I believe the cable used is RG136.

It's only RG58 for the Outdoor Home antenna.

Yeah, sorry I wasn't able to get better pics. My wife recently dropped the macro lens we had for our Canon. Was stuck with a wide angle or the zoom.

Dumb Question.
Why not just cut the wire a few inches from the adapter plug and strip the wires to solder the new mini plugs on? Rather than having to take the adapter apart.

If i don't find my soldering iron soon, i'm gonna buy a new one!

Nothing wrong with that either really. I just wanted to tear things apart to see what it looked like

Hey DaJoker, I emailed the transcript to ME_RUBIN from me and Brent Hagood at techtoolsupply.com for tools and everything else, hopefully we can get this going again.

Not sure what you are taking a pic of here, It sounds like you are taking apart a stiletto? I did this recently, see http://www.siriusbackstage.com/forum...ad.php?t=95436 I took a few pictures too. If anyone has any requests, I am willing to take it apart again. The antenna connector is very very small, you would need to have 3 hands and tweezer fingers to solder anything on there.

Franklin, I saw your post on the stiletto disection. Nice, No, what we are taking apart is the connector that plugs into the bottom of the unit for the antenna headphones. Go back and look at the post from DaJoker where he has made it possible to plug in an external antenna and a earphone jack into this connector.

Everything here is Outside of the Stiletto. Yours was inside.

Thanks for the offer!

Jason,

I spoke to Brent at Techtoolssupply and he is going to make me up the SMB connector with a foot of coax so All I have to do is solder the connector to the circuit board. He charged $11.89 shipped for it. Hopefully I should have it by the weekend.

BTW the connectors he charges $7.99 and he charges $32.99 for the crimp tool. His connectors only work with a certain kind of coax so that is why I did it that way.

DaJoker, Just to make sure, Is this what you mean how you would cut it if you wanted to make sure?




I picked this up at radio shack on the way home from work.



So I'll take it one step at a time and hopefully have a nice new connector for my stiletto.

I think I'm missing something here , instead of cutting the plug apart to get to the circut board wouldn't it be easier to go a foot or so away from the plug and cut the whole wire in half then slice down the side of the wire to locate the coax and install correct plug on the end of the wire and if ya wanted a plug for audio do it there also .
