Thanks all for the help Will be looking for a lead free solder to solder terminals to the radial wires
According to use 3.5 mm aluminum wire, what do you think? Is a good option or is better to use copper stranded cable? 73, Jorge CX6VM/CW5W -----Mensaje original----- De: Topband [mailto:[email protected]] En nombre de Gary Smith Enviado el: miércoles, 31 de diciembre de 2014 02:49 a.m. Para: [email protected] Asunto: Re: Topband: Silver solder I 2nd Merv's experience. My on the ground radials, on an oceanside salt marsh, have held up as new for 4 years and I used the lead free plumbing solder. The only issue is that solder requires a bit more heat then the leaded solder. That's all I use outdoors any more. 734 & HNY, Gary KA1J > Here in salt air regular solder turns to white powder pretty fast, I > have been also using lead free solder, I got a roll of plumbers > solder and a jar of resin flux. works very well on #10 radials and > 4 inch wide copper strap etc. Have left several joints exposed > and there is no corrosion after 4 years. > Works great so far. > 73 Merv K9FD/KH6 > > > 2% is about what the lead-free electronic solders are (they are a tin/silver/copper alloy and are mostly tin). Don't bother with the 30%. My mechanical contractor uses this stuff to fix things he can't reach well enough to braze. It's not generally used for anything normal. > > > > Coincidentally I was just out soldering more radials last night. I use 18 gauge solid copper radial wire and a 1/2" copper pipe ring to tie them together. My original 29 radials were all soldered with lead-free electronic solder and they are all fine after 2-3 years. I didn't do anything to try to protect the soldered connections -- everything is fully exposed and lying on the ground. > > > > I added 31 more radials. I soldered some the same way, but I'm trying regular lead-free plumbing solder on the others. I am finding the plumbing flux to work better than the rosin-core solder (it wets the joints more evenly). I'm not sure what the exact alloy is for the plumbing solder. > > > > If you use the solder bars remember that you'll need separate flux and brushes to apply it.
