Default Can you splice GPS Antenna Cable?

Accidentally cut the cable to the antenna, can it be spliced or do I need to buy another antenna and cable?

Thanks

Splice it. It will be fine.

You can splice it with no problems. I cut 10 feet or so out of mine and then soldered it with heat shrink and has worked perfect for years

Always best to solder connections when you can. However, a good crimp and tape job will work fine. Assuming you're not talking about NMEA 2000. Otherwise, all the responses so far are null and void.

No, just standard Garmin GPS cable on an old Garmin Unit. Thanks.

It's not always best to solder connections on a boat. For most, you SHOULD NOT solder. A very light-gauge wire like the GPS will be fine, but for the most part none of your DC power wiring and NONE of your AC wiring should be soldered - just mechanically crimped and adhesive heat shrinked if necessary.

Not sure what the NMEA 2000 comment means - CANbus is much more robust than the weak GPS signal and would be far less picky about the splice quality...

Since the subject was electronics wiring that was the focus of my reply and comment about soldering. Like most things, common sense should come into play. Few people would attempt to solder heavy AC power wiring but if you're splicing wire, small or large, a solder connection is seldom a bad idea.

Yes, splice solder and shrink tube the wires.

OK, I'll bite. Why not solder power wires?

To rigid can cause wire to part

As I said for the GPS wire it's fine, but you generalized "always best to solder connections when you can." Not true on a boat. Due to the vibrations, any solder that wicks into the wire can cause it to become "rigid" and act as a solid conductor. Solid conductors crack off on a boat when flexed where they are fixed.

In general, better to not solder and use a proper mechanical crimp. ABYC prohibits connections where solder is the primary mechanical connection, meaning you HAVE to crimp anyway and it must be strong enough to hold things physically.

Personally, on a boat I'd only solder connections too small to crimp, or specifically designed for soldering - VHF/GPS antenna connections, A/V wiring (like RCA cable ends), some NMEA 0183 wires, etc.

So Lucille, are you saying that you would or would not solder a GPS antenna connection? IF not what kind of crimp do you recommend?

Thanks,

Thanks,
To make it simple--solder the gps--DON'T solder your battery cables

Nope, sorry. Go right ahead and solder the antenna connection.

So what you are saying is to just lick my fingers and hold the wires? sounds simple enough
