[TowerTalk] DAVIS RF CO. response to FLEX-WEAVE Tm and Aerial WireRecommendations

[Dennis OConnor]

I don't know what Davis RF will recommend to resolder fine stranded wire that has become oxidized, but this old industrial electrician has had to do that in the distant past...  My method is
  1. comb /cut away, any fuzz that cannot be tamed, and otherwise straightened on the broken ends....
  2. Dip into a container of muriatic acid - only to the depth that matches the intended length to be soldered <brief dip>, the copper will immediately brighten - do not leave it in the acid as it will eat the copper...
  3. Immediately dip in a solution of water and Arm&Hammer Baking Soda to twice the previous depth...  Leave this awhile to be sure of neutralizing the acid...
  4. Gently warm until the copper is dry (heat gun)...
  5. Dip the warm copper into solder flux...
  6. Now twist the wire ends until as flat, straight and manageable as possible, then twist the two broken ends together - use the Ma Bell method..
  7. Solder with a gun with adequate heat - borrow or buy if you don't have at least a 250 watt electric gun - I like the butane catalytic torches, especially for outdoors...
  8. Clean flux residue off with a solvent, spirits, or MEK...
  9. Use liquid tape to seal the joint, then overwrap with 3M  #33 electrical tape...
