Default Home Antenna cable splice question

I've run into a problem getting the connector of a home antenna through the window in my office. I don't want to drill any holes in the window frame. There is a small space that I can almost get the connector through.......almost. If I cut the cable and then splice it once I get it under the window, I think this will work. But, I have a question about the number of conductors in the cable.

I'm using a sirius home antenna. I took it apart trying to determine if I could disconnect the cable from the antenna side. No luck. The cable is soldered to a large plate and a chip. I think if I desoldered the cable, I'd likely screw it up. I took a multi-meter to the connector. There is continuity between the outer shield and the inside sleeve. That would suggest only 1 conductor in the cable. But, There is a nylon cable in the center of the cable and inside the nylon cable there appears to be a copper conductor. There is no continuity between the outer shields and this conductor. And, I can't seem to find the other end of this copper conductor on the antenna end..........unless it is soldered into the center chip. Does anyone know how many conductiors are inside the cables for these antennas? Any ideas on how I can cut the cable and then use connectors at the splice so that the antenna will deliver a signal to the receiver without signal loss?

Thanks,
Bob

Do not cut that cable. You will never get it back together correctly.

OK, maybe I'm wrong. If you can follow these directions, then you can install connectors... it's a PDF...

do those plug right into the radio, or do you put two and join together..??

@kitchin
Thanks for the reply and info. This looks like it will solve the problem. Now all I have to do is try to buy less than a lot of 100

@gjxj
The technical info indicates that these are crimp on connectors. They plug right into the radio. In my situation, it means that I will have to cut the connector off the cable and discard the connector. Then, snake the cable through the window frame, and then install the crimp on connector. The only hassle is correctly trimming the cable and then crimping. Some applications require a special crimping tool. This all translates into unnecessary expense.

By the way, if you are inclined to get into the body of the antenna, you will need special screwdriver bits, the type that are used for tamper proof fasteners. I found the bit at a local tool store. But, I can tell you it is not an easy item to find. Using any other method to open it up will result in a mess.

You can cut the cable and fit it wherever you need for your app and splice it back with care. Tools required- soldering iron, solder,shrink tubing and 15 minutes of your time.
BTW I have done this half a dozen times and doesn't affect signal reception. I'm in the process of buying about 15 connectors, male and female, crimper and some wire to make my own because you just don't need 50' all the time

@dnmal1
So, based on your experience, I don't even need a connector. I can just splice the two conductors. I'm curious though. If 'you just don't need 50' all the time', why are you using connectors? Why don't you just cut out the unnecessary cable and splice as you suggest?

That is correct you don't need a connector, just splice. I have have mishaps with antennas a lot ranging from wire pullled out from smb connector and wirebeing sheared off for whatever reason. I'm in the construction field and my boom box goes everywhere and gets much wear and tear. So basically I want the means to fix whatever might come up so I don't have to be without my Sirius because I couldn't deal with that. :\ Hope this makes things more clear, sorry

Thanks for the clarification dnma1. I know what you mean about being without Sirius. It's like going through the work day without breakfast and lunch?

I hear a lot of other workers listening to their regular radios, I just shake my head and laugh. Other workers like coming to where I'm at and listen
