Here is a good source for antenna wire to make a "long wire" type antenna. For that use I would recommend their type 511, which is 7 strands of copper plated steel wire, 14 gauge total size. https://www.thewireman.com/antennap.html . They also carry insulators, ground rods, etc. https://thewireman.com/antacc.html#1 . You can also find the old fashioned glass antenna insulators as well as the old style lightning arrestors on eBay, which is where I have bought them, being something of a traditionalist. You may have to rebuild the lightning arrestors though, which is very easy compared to restoring a radio. For the lead in from the antenna I recommend 14 gauge stranded copper wire, the kind used in automotive work, which you can buy pretty cheaply. Since the type 511 wire above is copper plated, it will be pretty easy to solder the lead in to it.
