I realise having an inline Belling-Lee connector isn't ideal, the more so as it only connects to a 50cm extension with a BNF plug on the radio end. This setup was in the Libelle when I bought it, seems to work OK, and so it has stayed there. The short extension is necessary because otherwise the cable wouldn't reach the radio, let alone allow the panel to slide out far enough to connect or disconnect it from the radio. I've thought about replacing it, but the free end of the original cable is in under the front coaming, too short to reach daylight. I'm not keen on making a solder joint in there, which would probably be no better electrically than leaving the Belling-Lee in place. Last but not least, I don't fancy pulling and replacing the entire cable either. -- If the connector doesn’t need to come apart then you could simply wrap it in a couple of turns of self amalgamating tape, that would be totally waterproof and airtight, also it can be cut off if you did need to disconnect it. Ben. Sounds good to me. Thanks. -- Martin | martin at Gregorie | gregorie dot org I have always prefered Internally-Glued Heat-Shrink over Tape. But getting back to the original posting, we should never recommend Belling-Lee and only use where there is no alternative. Tim Newport-Peace http://www.newportpeace.co.uk/icom.htm Agreed - obviously an extra 50cm of uncut cable with just a BNF on the end would be a lot better, but, as I said, I really don't want to mess about with soldering etc in mid-air on a piece of cable that comes out near the front end of the right side instrument panel support channel. However, if you can point me at a description of how to to use 'Internally-Glued Heat-Shrink over Tape' after, presumably, soldering the internal wire ends together, that would be interesting to know. Would it be easier than making upo some sort of clip to lock the B-L halves together? I had in mind sleving the Belling Lee with Heatshrink and the internal glue will seal to the outer of the co-ax eat each end. That should be moisture-proof. I would Never suggest splicing co-ax. However, another possible solution would be to use: https://tinyurl.com/tseyff8 or similar. No Soldering required. I don't particularly like these, but I like Belling Lee even less. At least you will be using a 50Ohm connector which is moisture proof. Tim Newport-Peace http://www.newportpeace.co.uk/icom.htm |

Are you talking about a a disconnect on a wire going to a GPS antenna ?
Sorry about my ignorance regarding anything electrical. Dan |

Thanks !
What about cutting and reconnecting (quick disconnect) the GPS antenna wires. What connector would you use ? Dan |

On GPS antennae, for what it's worth:
I opened a GPS puck antenna used for my PowerFlarm Portable, unsoldered the wires, cut the coax to the required length and soldered the center conductor and shield to the correct locations. I often had GPS dropouts on the Flarm.Â* I recently removed that antenna and, using the internal antenna on the portable unit, have had no more drop outs.Â* Just sayin'...

I suppose that depends on what you're connecting the GPS antenna to and what sort of connection it uses. My RedBox FLARM has a BNF socket for the GPS puck connection. The supplied puck had way to much wire for my installation, so I cut the wire on a Gilsson puck down to 150mm (6") and soldered a right-angle BNF plug onto it. The FLARM system works perfectly. OTOH my EW logger uses a small brass? gold-plated? screw-on antenna connection. I didn't have ant replacements, so this time I wound the excess cable up into a neat 'donut' secured with a couple of cable ties, clipped the supplied ferrite core over the logger end, connected it all up and again it works very well. -- Martin | martin at Gregorie | gregorie dot org |

Thanks for pointing to my presentation on wiring at http://aviation.derosaweb.net/presentations/#wiring. Please let me know if there are corrections to be made (and there are ALL-WAYS corrections to be made).
Also, not to toot my own horn too loudly, but I will be speaking on this topic at the 2020 SSA Convention in Little Rock, Arkansas on Saturday, Feb 22 at 1:30PM in Ballroom B. I really don't want to find myself speaking only to the hotel security staff so I truly hope to see and meet all of you there! - John DeRosa OHM Ω |
