To Solder or Not Solder the Ends of Stranded Antenna Wire ?
I was taught many years ago that it was always a good Idea to Solder the Ends [1/2"~1" of my Stranded Antenna Wire to Electrically Bond them on both Ends in case any individual strands should break. + Plus on the Feed-End the Soldered Stranded Wire made for a better Mechanical Connection to the Hardware. * Also the claim is that the Solder & Iron/Steel/SS 'connection' was less likely to Corrode then Copper & Iron/Steel/SS. ? Is Soldering the Wire Ends common practice ? =Alternatively= I have been told to only Solder the Stranded Antenna Wire at the Feed-End; and then Tie-a-Knot in the Far-End about an Inch or two from the End {Overhand Knot or Loop Knot} -and-then-to- Separate-out the individual wires into a Porcupine {half-ball} so that the Static Electricity could bleed-off and reduce some of the the static 'noise' on the Antenna Wire. ? Does splaying the Far-End Antenna Wires really help to Bleed-off the Static build-up on the Wire ? thinking about the things i do . . . and the why of it all ~ RHF |

Use a thimble and clamps to secure the wire mechanically to an insulator. Then solder your 9:1 balun hot primary positive lead to the antenna wire. You'll need still air, or a 100 Watt iron. |

It is the free "Tag" End that gets Soldered and Secured to the Matching Transformer Hardware or Wire; or to the Center Wire of the Coax Cable. Same on the Far-End the Antenna Wire goes around {thru} the End Insulator first. Then the free "Tag" End that gets Soldered about two Inches back for 1/2" ~ 1" and the un-soldered Tip Wires are spread-out to bleed-off the Static [ESD] Clearly Solid {Single Strand} Wire does not need to be Soldered. Most likely common 7-Strand {12-Strand} Two Layers 1+7 -or- Two Layers 3+9 commercial Electrical Wires may or may not need to be Soldered to get every Strand in the Bundle 'connected' and working as one "Bonded" Antenna Element. But the 19-Strand commercial Electrical Wires are usually Three Layers of 1+7+12 and not all of the Wires may be 'connected' without Soldering them all together at some point {spot} on the Length to Electrically "Bond" them as one Wire. Now when using a Stranded Antenna Wire like Flex-Weave with 168 Strands or 259 Strands http://www.radio-ware.com/products/fw.htm -imho- Soldering can help in getting each and everyone of those 100+ Individual Stranded Wires 'connected' and working as one fully "Bonded" Antenna Element. ~ RHF |

... Never heard of such a thing. I use insulators at each end, and in the old days I used a neon bulb or a 12V tail light bulb as a bleed off. I went to gas discharge tube arrestors a long time ago. The 12V bulb made a really nice light show on winter days when the wind was really going. What kind of buld exactly is a "12V tail light bulb"? -- Brian Gregory.

An automotive 12 volt, 5 watt bulb (globe) with (usually) a bayonet fitting. You can get bulbs that have dual filaments, one filament for tail lights, the other for brake or indicator lights. The brake/indicator light filament has a higher wattage rating (21 - 25 Watts) so the bayonet typically has staggered locating pins. This prevents the higher wattage rating being used as the tail light filament. http://www.eziautoparts.com.au/light...or-globes.html New technology is seeing the incandescent bulbs being superseded by LED arrays.

So I think BDK must mean something else. Either that or he's making it up as he goes. -- Brian Gregory. (In the UK) To email me remove the letter vee. |

What kind of buld exactly is a "12V tail light bulb"? -- Brian Gregory. (In the UK) To email me remove the letter vee. The 12 VDC Auto Tail Light Bulb has a Tungsten Element which is a relatively High Resistance and functions as a constant {always-on} bleed resister to drain any static electricity before it could build-up. Cheaper that a Resister and the Mini-Coils of the Tungsten Element was way far beyond the HF Band so it only functioned as a Resister and not a Coil {Inductor} when used with a SWL [HF] Antenna. ~ RHF Never saw one of these 12 VDC Tail Light Bulbs 'glow' because they were constantly bleeding-off the Static Electricity before it had a chance to build-up -but- using a Neon NE-2 Bulb will 'glow' if the Static Electricity does build-up to trigger it. That is why using an NE-2 Neon Bulb by itself is not recommended since it is designed to Fire only after the Static is already built-up. Using a NE-2 Neon Bulb with a Bleed Resister is often done with the idea that the NE-2 is an Overload 'fail-safe' should the Bleed Resister fail of there is a not to distant Lightning Strike. If you are already using a Matching Transformer Balun/Unun with your SWL Antenna the the Bleed Resister generally is not needed or required. ~ RHF |
