I am making a 40M double extended zepp from bare copper-plated steel
wire (26 ga). The wire will be on two reels, each reel holding 87 ft. I will also be able to use this arrangment to make shorter, resonant antennas. However, the reel is too small to hold 135 ft of wire, which is the next useful length (160M resonant). What is a good way of adding a 48 ft wire tail to the wire on the reel if I find myself on rare occasion wanting to use 135 ft. wires? I am thinking of crimping and soldering small eyes to the wire ends and joining them with a small stainless nut and bolt. I figure this will take some tension. Is there a better way? An unrelated question: If it becomes necessary to splice this wire permanently, what is a good way of doing it? Will soldering a twisted 1/2" overlap do the job? How do I keep the solder from tinning (and stiffening) the wire near the joint? Is there a chemical that will repel the solder (anti-flux)? Heat sinks?

Since your wire is so lightweight, only 26 ga., banana plugs/jacks might work. Otherwise, the stainless nut/bolts should do the trick. It shouldn't take much -- I've added tails to my dipole with alligator clips. Bob k5qwg Ken KC2JDY Ken (to reply via email remove "zz" from address) |

Hi Ken, By the book, such a join would be done with a "Western Union Splice." This is a join that would be several inches long: ----------------------------- -------------------------------------- the first overlap of wires would be three or so turns loosely twisted about each other; ----------------////----- -----\\\\---------------------- each tail would then be tightly twisted in at least three turns around the wire it parallels. -------------XXX/\/\/\XXX------------- 73's Richard Clark, KB7QHC |

![]() Ken, Your idea with the nut/bolt should work, or, just solder the 'tail' on. Any soldered joint is going to be a bit 'stiffer' than the rest of the antenna, so keeping the joint as short as possible would probably be less 'stiff' than a longer one (not really, but easier to manage, maybe). If you had another couple of reels, put the 160 meter tails on them and use the reel(s) to 'chunk' over a tree limb. Make the connections with the 'free' ends of the tails... 'Doc |

"Smallest Nicopress I could find was 1/32" (.031") cable, 26 ga." That`s pretty small. If you don`t Nicopress, the "Western Union Splice" is a good alternative. It is shown on page 20-4 of the 19th edition of the ARRL Antenna Book as Fig 3. A copper-wire Table on page 20-2 relates wire size in AWG / B&S to English and Metric sizes and other characteristics. Much good information is in the 19th edition of the ARRL Antenna Book, Chapter 20, for those who would hang wires, rods, or tubing in the air. Best regards, Richard Harrison, KB5WZI |
