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?

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.

18 gauge solid copper radial wire and a 1/2" copper pipe ring to tie them

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.

regular lead-free plumbing solder on the others. I am finding the plumbing

evenly). I'm not sure what the exact alloy is for the plumbing solder.
